a The Iraqi Government formally declared victory on 10 July 2017,[10][11] but the fighting continued,[58][59] with heavy airstrikes and shelling,[60][61][62] until 20 July.[14][15][63] The Iraqi military and CENTCOM said that these were "clearance operations."[64][65]

The Battle of Mosul (Arabic: معركة الموصل, Ma'rakat al-Mawṣil) was a major battle initiated by the Iraqi Government forces with allied forces^[a] to retake the city of Mosul from the Islamic State (ISIL), which had seized the city years prior in June 2014.^{[66][67][68][69]} It was the largest conventional land battle since the capture of Baghdad in 2003.^[70] It was also the world's single largest military operation overall since the 2003 invasion of Iraq and was considered the toughest urban battle since World War II.^{[43][71][72][73]}

The operation, which was called Operation "We Are Coming, Nineveh" (قادمون يا نينوى; Qadimun Ya Naynawa),^[74][75] began on 16 October 2016, with forces besieging ISIL-controlled areas in the Nineveh Governorate surrounding Mosul,^[76][77][78] and continued with Iraqi troops and Peshmerga fighters engaging ISIL on three fronts outside Mosul, going from village to village in the surrounding area in the largest deployment of Iraqi troops since the 2003 invasion of Iraq.^[79] At dawn on 1 November 2016, Iraqi Special Operations Forces entered the city from the east.^[80] Met with fierce fighting, the government advance into the city was slowed by elaborate defenses and by the presence of civilians,^[81] but the Iraqi Prime Minister Haider al-Abadi declared "full liberation of eastern side of Mosul" on 24 January 2017.^[82] Iraqi troops began their offensive to recapture western Mosul on 19 February 2017.^[83]

On 9 July 2017, the Iraqi Prime Minister arrived in Mosul to announce the victory over ISIL, and an official declaration of victory was proclaimed on 10 July.^{[10][11][84][85]} However, heavy clashes continued in a final pocket of ISIL resistance in the Old City, for almost another two weeks.^{[14][15][16][86]} It was estimated that removing the explosives from Mosul and repairing the city over the next five years would require $50 billion (2017 USD),^[87] while Mosul's Old City alone would cost about US$1 billion to repair.^[11]

The Battle of Mosul was concurrent with the Battle of Sirte (2016) in Libya and the Raqqa campaign (2016–17) conducted by the Syrian Democratic Forces (SDF) against ISIL's capital city and stronghold in Syria.^[88]

In 2017, John Spencer listed Mosul as one of the cities destroyed by violent combat, joining battles such as Stalingrad, Huế, Grozny, Aleppo and Raqqa.^[89] It has been referred to as a "modern day Verdun".^[90] During the battle, top coalition commander, Stephen J. Townsend, stated that it was "the most significant urban combat to take place since World War II".^[91]

Mosul is Iraq's second most populous city. It fell to 800–1,500 ISIL militants in June 2014, because of the largely Sunni population's deep distrust of the primarily Shia Iraqi government.^[31][92] It was in the Great Mosque in Mosul that ISIL leader Abu Bakr al-Baghdadi declared the beginning of ISIL's self-proclaimed "caliphate" which spans Iraq and Syria.^[92] The original population of 2.5 million fell to approximately 1.5 million after two years of ISIL rule. The city was once extremely diverse, with ethnic minorities including Armenians, Yazidis, Assyrian, Turkmen and Shabak people, all of whom have suffered under the (majority Sunni Arab) Islamic State.^[93] Mosul was the last stronghold of ISIL in Iraq,^[94] and the anticipated offensive to reclaim it was promoted as the "mother of all battles."^{[95][96][97][98]}

In the weeks leading up to the ground offensive, the U.S.-led CJTF–OIR coalition bombed ISIL targets, and the Iraqi Army made gradual advances on the city.^[79] Royal Air Force's Reaper drones, Typhoons, and Tornados targeted "rocket launchers, ammunition stockpiles, artillery pieces and mortar positions" in the 72 hours before the ground assault began.^[99] Leaflets dropped on the city by the Iraqi military advised young male residents to "rise up" against ISIL when the battle began.^[94] To prepare defenses against the assault, ISIL operatives dug four-square-metre holes around the city, which they planned to fill with burning oil to reduce visibility.^[79] They also built hundreds of elaborate tunnels in the villages surrounding Mosul, rigged with explosives and booby-traps, and laid Improvised explosive devices (IEDs) and land mines along the roads.^[100] There was considerable concern that ISIL might employ chemical weapons against soldiers and civilians.^[101]

According to Iraqi sources, the assault towards Mosul was being waged from Al-Khazer axis (east of Mosul), Mosul Dam (northern axis), Baashiqa axis (eastern axis), Al-Qayyarah axis (southern axis) and Talul el-Baj- Al-Khadr axis (southwestern axis).^[102]

About 3,000–5,000 ISIL militants were estimated to be in Mosul city, according to the United States Department of Defense.^[103] Other estimates ranged as low as 2,000 and high as 12,000 ISIL fighters.^[31][34] Mosul Eye estimated approximately 8,000–9,000 fighters loyal to ISIL, with "half of them... highly trained, and the rest... either teenagers or not well trained. About ten percent of the fighters are foreign (Arabs and non-Arabs). The rest are Iraqis. Most are from Nineveh's townships and districts."^[104] Prior to the start of the battle, in late September 2016, it was estimated that around 20,000 ISIL fighters were living in Mosul,^[105] many of whom later fled the city to Syria and Ar-Raqqah, when Iraqi forces began to besiege Mosul.^{[citation needed]} The IS garrison was led by several commanders. For much of the battle, Ahmad Khalaf al-Jabouri (an Iraqi ex-special forces officer) acted as main military commander; Iraqi security analyst Hisham al-Hashimi described al-Jabouri as an overall capable militant leader.^[26] Another local IS officer was Aymam al-Mosuli (nicknamed "ISIS Rambo"), a bodyguard of Abu Bakr al-Baghdadi and head of the special security units.^[27] According to a pro-IS source, al-Baghdadi's deputy Amir Mohammed Abdul Rahman al-Mawli al-Salbi was also involved in the battle.^[25]

The Iraqi-led coalition was initially estimated by CNN to have 94,000 members.^[106] but this number was later revised upward to 108,500;^[28] 54,000 to 60,000 Iraqi security forces (ISF) soldiers, 16,000 Popular Mobilization Forces (PMF) fighters (also referred to as PMU), and 40,000 Peshmerga (including approximately 200 Iranian Kurdish female fighters from the Kurdistan Freedom Party (PAK))^[107] were deployed in the battle.^[29] The Iraqi and Peshmerga forces deployed for the Mosul operation were estimated to have outnumbered the ISIL militants present by 10-to-1.^[43]

Among the PMF units, the Nineveh Plain Protection Units composed of Assyrians were among the paramilitary forces in the government coalition.^[108][109] Shia militias, including several brigades of the paramilitary organization Hashd al-Shaabi, the Peace Companies, Kata'ib Hezbollah, the League of the Righteous, the Badr Organization, Saraya Ashura, Saraya Khorasani, Kata'ib al-Imam Ali, Harakat Hezbollah al-Nujaba and Turkmen Brigades also took part.^[110][111] The Ezidi community of the Sinjar region contributed the Sinjar Resistance Units (YBŞ) and Êzîdxan Women's Units (YJÊ),^[112] which operated in concert with Sunni Arab Shammar tribal militias and People's Defence Forces (HPG) of the Kurdistan Workers' Party (PKK).^[113] Other Assyrian forces involved in the planned offensive included the Nineveh Plain Forces (NPF) and Dwekh Nawsha, who are allied to the Peshmerga.^[114][115]

An international coalition of 60 nations, led by the United States, supported Iraq's war against ISIL, providing logistical and air support, intelligence, and advice.^[116] The international coalition forces were headquartered 60 kilometres (37 mi) south of Mosul at Qayyarah Airfield West (or Q-West) in Qayyarah, which was retaken from ISIL in June.^[117] About 560 U.S. troops from the 101st Airborne Division were deployed to Q-West for the battle, including command and control elements, a security detachment, an airfield operations team, and logistics and communications specialists.^[118] The U.S. deployed HIMARS rocket launchers and M777 howitzers, manned by the 101st's 2nd Brigade Combat Team and the Golf Company, 526th Brigade Support Battalion. The British deployed several elements of the United Kingdom Special Forces as well as several L118 light guns. The French army deployed four CAESAR howitzers and 150 to 200 soldiers at Qayyarah, with 600 more French troops announced at the end of September.^[119]

An additional 150 French soldiers were in Erbil, east of Mosul, training Peshmerga.^[111] The aircraft carrier Charles de Gaulle, with a squadron of 24 Rafale M jets, was deployed from Toulon to the Syrian coast to support the operation against ISIL through airstrikes and reconnaissance missions; 12 other Rafale jets operated out of French Air Force bases in Jordan and the United Arab Emirates (UAE).^[120][121] Eighty Australian special forces soldiers and 210 Canadian Special Operations Forces Command (CANSOFCOM) soldiers were also deployed to assist the Peshmerga. In addition, the Canadian Forces 21 Electronic Warfare Regiment was also reported to be in the area, working to intercept and relay ISIL communications, while a Role 2 Canadian Army field hospital with 60 personnel was set up to treat Peshmerga casualties.^[122][123]

The Ba'ath loyalists group, known to be led by Saddam Hussein's former vice president Izzat Ibrahim al-Douri, issued a statement before the start of operations calling for the people of the city to start an uprising against ISIL and announced that they will fight the terrorist organization.^[124][125]

On 16 October 2016, Iraqi Prime Minister Haider al-Abadi declared the beginning of the assault to recapture the city of Mosul.^[78] Officials reported howitzers firing on ISIL targets later that day.^[76] The Iraqi Armed Forces began the main assault on 17 October at approximately 6 a.m., local time,^[94] with shelling and the arrival of armoured vehicles to the front lines.^[126] The Peshmerga in the Khazir region, east of Mosul, started the ground assault by advancing on ISIL-held villages from three fronts, while Iraqi security forces advanced from the south.^[127] Iraqi troops advanced on the Bartella area east of Mosul while ISIL fighters fired mortars at Peshmerga.^[128] The President of KRG, Massoud Barzani, said that Peshmerga and Iraqi government fighters retook 200 square kilometres (77 square miles) from ISIL on the first day of fighting.^[129] Iraqi government officials reported inflicting severe casualties and destruction of equipment on ISIL forces in the Hamdaniya district southeast of Mosul. Wounded ISIL fighters reported to have been transferred to their de facto capital Raqqa, in Syria, for medical aid.^[29] Some ISIL fighters were reported shaving their beards and getting rid of their Afghan uniforms.^[130] Mosul's "Freedom Bridge" was destroyed in the fighting.^[131]

On 18 October, the Iraqi government declared to have captured 20 villages from ISIL within 24 hours of fighting.^[132] On the southern front, Iraqi troops retook several villages near Qayyarah, including al-Sirt, Bajwaniya, al-Hud and al-Mashraf, and parts of the al-Hamdaniya District southeast of Mosul.^[133] as well as the al-Shura district.^[134] Iraqi Federal Police also regained control of 56 oilfields in the Qayyarah district.^[133] According to reports, the Peshmerga met little resistance on the eastern front, while Iraqi and PMF fighters coming from the south faced tougher resistance from ISIL.^[135] Iraqi Army forces stormed Qaraqosh (Bakhdida), once the largest Assyrian town in Iraq, and fought with ISIL fighters who remained holed up, while also Hammam al-'Alil.^{[136][137][138][139]} The Iraqi and Peshmerga advance had been slowed down during the same day due to suicide bombers, roadside IEDs and oil fires, and the allied forces were carrying out street-by-street search operations to clear out ISIL forces from the outskirts of Mosul city.^[140][141] The Peshmerga later paused their advance while the Iraqi Army continued its advance.^[142]

At this point in time, the coalition strategy was reported to be to encircle Mosul completely, after which Iraqi troops would advance into the city center.^[143] As the Iraqi Army advanced on Mosul, rebellion against ISIL broke out in the city, though ISIL forces put down the revolts within a couple of days.^{[144][145][146]}

The Iraqi Army resumed fighting on 19 October, surrounding Qaraqosh, while ISIL deployed snipers and car bombs.^[147][148] Lt. Gen. Qassim al-Maliki declared that Iraqi forces had captured 13 villages north and northeast of Al Quwayr, south of Mosul, and the Iraqi Army was reported to be within six kilometres (3.7 mi) of the outskirts of Mosul city.^[149] The village of Kani Harami was captured after heavy fighting in the morning with the militants retreating to Abbasiyah.^[150] A total of 22 towns were reported to have been captured, with 12 by the Peshmerga and 10 by the ISF.^[151] Nofal Hammadi, governor of the Nineveh Governorate, declared that 40% of the province had been retaken from ISIL.^[152]

The offensive to retake the town of Bashiqa northeast of Mosul was delayed due to lack of logistical support.^[153][154] The international coalition's commander Gary Voelsky also stated that a majority of ISIL leaders were fleeing Mosul, and predicted that foreign fighters would form the majority of militants remaining in the city.^[155][156]

The fighting intensified on 20 October.^[157] A large convoy of Golden Division arrived at positions retaken by the Peshmerga forces,^[158] and they also captured Bartella.^[159] According to Maj. Gen. Maan al-Saadi of the Iraqi Army, 200 ISIL fighters were killed in the fight for Bartella.^[157] The Peshmerga and NPF announced a "large-scale operation" to the north and northeast of Mosul, to retake the Assyrian towns of Tesqopa and Bashiqa.^[156][160] During the day, the Peshmerga captured six villages, including four on the Bashiqa front line and two on the Nawaran front, while entering another four villages. The Peshmerga briefly captured the village of Tiz Khirab but were forced to withdraw.^[161] On the southern front, Iraqi forces resumed their push north after a brief pause^[162] and recaptured six villages east of Qayyarah.^[161]

ISIL committed another war crime by setting the Al-Mishraq sulfur plant on fire, causing two deaths and nearly 1,000 hospitalizations from sulfur fume inhalation.^[163] The group was also reported to be digging trenches to slow the advancement of coalition troops.^[164]

On 21 October, ISIL launched multiple attacks in Kirkuk to divert military resources. Multiple explosions and gun battles were reported in the city, mostly centered on a government compound, and a senior Peshmerga commander said that the attackers had entered by posing as IDPs.^[165] Meanwhile, Iraqi government forces reported that they had retaken 2 more villages south of Mosul and killed 15 terrorists.^[166]

On 22 October, Iraqi police declared that ISIL's attack on Kirkuk had been repelled and that all the attackers had been killed or had blown themselves up.^[167] Iraqi officials also stated that 80 people were killed in Kirkuk, primarily Kurdish security forces, and about 170 wounded; 56 ISIL militants were also killed.^[168] A reporter of Türkmeneli TV also died in the attack.^[167] while at least seven journalists were wounded.^[169] On the same day, Iraqi forces launched a large-scale offensive began to retake the Assyrian town of Bakhdida, which had remained under ISIL control after several days of fighting.^[170] Iraqi troops also advanced on the town of Tel Keppe, to the north of Mosul.^[171] On 23 October, the Peshmerga General Command also stated that the Peshmerga had cordoned off eight villages and had secured a significant stretch of the Bashiqa-Mosul highway, coming within nine kilometres (5.6 mi) of the city.^[172] ISIL increased its counter-attacks in order to distract the pro-government advancing towards Mosul. In addition to the attack on Kirkuk on 21 October, ISIL fighters struck Ar-Rutbah in Anbar Province, as well as Sinjar.^[173]

By 24 October, nearly 800 ISIL militants had been killed while 78 villages were reported to have been retaken from the group.^[174] The attack on Kirkuk was also brought to an end on the same day, with 74 militants being killed and others, including the leader of the attackers, being arrested.^[175] On 25 October, Iraqi Special Operations Forces came within two kilometres (1.2 mi) of the city and paused their advance to wait for reinforcements.^[176] On 26 October, Iraqi forces faced heavy resistance from ISIL as they attempted to clear the militants from villages in Shora, south of Mosul.^[177] Hundreds of ISIL suicide bombers were also reported to have been sent from Syria to defend Mosul.^[178] Meanwhile, Peshmerga forces captured the village of Derk, 12 kilometres (7.5 mi) northeast of Mosul, where they discovered a large ISIL tunnel containing a large cache of weapons.^[179] On 27 October, the head of the United States Central Command, Gen. Joseph Votel, estimated that 800–900 ISIL militants had been killed in the battle.^[180] On 28 October, Iraqi forces recaptured the town of Al-Shura, south of Mosul.^[181] while joint Iraqi-Peshmerga forces captured Fadiliya, which lies just four kilometres away from Mosul.^[182] Meanwhile, the UN stated that ISIL had taken tens of thousands of civilians to use as human shields in Mosul, including at least 5,000 families from around Al-Shura and 2,210 families from the Nimrud area of Hamdaniya. Those who refused to go were executed.^[181][183]

On 29 October, the PMF launched an offensive towards the west of Mosul, with the aim of capturing the villages west of Mosul and reaching the town of Tal Afar, in order to prevent ISIL fighters from retreating into neighboring Syria or reinforcing their defense of Mosul. The PMF had been tasked with recapturing around 14,000 square kilometres of territory from ISIL,^{[184][185][186]} though they stated that they would not enter Mosul city itself.^[187] Meanwhile, the Iraqi Army and PMF captured 15 villages from ISIL.^[186]

On 30 October, the Peshmerga had captured six more villages to north and east of Mosul, and had seized control of several major roads and landmarks,^[188] and they declared to have captured 500 square kilometres of territory since the operation began.^[189] On the same day, the PMF stated that they had captured eight more villages to the southwest of Mosul.^[190] On 31 October, a major Iraqi operation was launched on Bazwaya, to the east of Mosul, capturing the town along with several nearby villages, after coming under heavy fire.^[191] After capturing Bazwaya, ISOF were less than one mile (1.6 km) from Mosul.^[192] Several Iraqi military officials stated that ISOF would soon begin its push into Mosul city.^{[193][non-primary source needed][194][non-primary source needed][195]} Meanwhile, the U.S.-led coalition stated that they would target ISIL militants from the air if they attempted to flee the city, though the U.S. Department of Defense stated that hundreds of militants were believed to have already escaped.^[196] Iraqi Prime Minister Haider al-Abadi meanwhile called on ISIL fighters in Mosul to surrender.^[192]

On 1 November, the operation to enter Mosul city began at dawn. The allied forces began their assault in Mosul's eastern Karama district, with artillery, tank and machine-gun fire on ISIL positions as they prepared the larger push into the city.^[197] Airstrikes by the U.S.-led coalition targeted ISIL positions, and ISIL started tire fires to reduce visibility.^[80] Heavy fighting occurred in the Gogjali district, at the gate of the entrance to eastern Mosul, where ISIL militants used car bombs and sniper fire to try to halt the advance.^[198] The Golden Division entered Mosul's city limits that afternoon, engaging in street fights with ISIL militants.^[198] Shortly afterward, the Iraqi Army announced that they had captured Mosul's state television building on the city's left bank.^[199][200] The Gogjali district was reported to be under Iraqi government control by the evening, while the Iraqi Army's 9th Division and 3rd Brigade had entered the neighborhood of Judaydat al-Mufti on the left bank. The Iraqi war media office stated that Iraqi government forces suffered no casualties during the assault.^[198][201] Meanwhile, Iraqi government forces captured two villages on the northern front.^[198]

On 2 November, ISOF continued fighting the remaining ISIL fighters in the eastern section of Gogjali,^[202] though Iraqi troops were forced to hold their positions in eastern Mosul, as poor weather conditions were limiting visibility for drones and aircraft, preventing them from advancing.^[203] Meanwhile, eight militants were killed in Mosul by Iraqi forces.^[204] On the same day, the PMU announced that it had captured 115 square kilometres that day after fierce fighting with ISIL, including six villages, and had surrounded three ISIL-held villages. They also claimed that they had reached a highway to the southwest of Mosul and had cut the first supply line to Mosul from Raqqa.^[202] In the southern front, the Iraqi Army launched an offensive in the morning to recapture Hamam al-Alil and engaged in heavy fighting with ISIL,^[205] while the Iraqi Federal Police captured two villages in the south.^[202]

On 3 November, the Iraqi Army's 9th Armored Division was reported to have entered the neighborhood of al-Intisar in eastern Mosul.^[206] while Mosul's Fifth Bridge, located over the Tigris river, was destroyed by airstrikes.^{[207][non-primary source needed]} U.S. and Iraqi authorities stated the offensive was "ahead of schedule", while Brigadier Saad Maan stated that the priority of protecting civilian lives and infrastructure would possibly slow their advance into the city.^[208] On 4 November, the Iraqi Army recaptured six districts in Mosul, including 90% of the eastern district of al-Zahra. However, they were forced to withdraw from Karama district because of heavy resistance.^[209] Clashes continued into 5 November, with clashes being the most intense in the neighborhood of al-Bakr.^[210] The eastern neighborhoods of Kirkukli and al-Zahra in the east and Al-Tahrir in the northeast were under Iraqi control, while the southern neighborhoods of Qudes and Karama reportedly remained under ISIL control.^[211] Fighting resumed in the Gogjali district, after ISIL militants emerged from tunnels during the night.^[212] The Iraqi Army continued its assault on three fronts to Hamam al-Alil,^[211] with Iraqi forces retaking the town by nighttime, though fighting would continue for another two days.^[212] On 6 November, Iraqi forces in the southwestern front stated that they were 4 kilometres (2.5 mi) from Mosul International Airport, after taking control of Hamam al-Alil on the previous day.^[213] They also stormed the Al-Sada district, their first entrance into northern Mosul.^[214]

On 7 November, the Peshmerga, backed by coalition airstrikes, launched an offensive from three fronts in the morning to take the town of Bashiqa, which was still held by ISIL and had been surrounded for about two weeks.^[215] About 100 to 200 ISIL militants were estimated to be left in the town.^[216] In the early afternoon, the Iraqi troops also advanced on the town of Tel Keppe, north of Mosul, besieging the town. The town of Bashiqa was reported to be fully under Peshmerga control, though an ISIL pocket remained under siege in the town until the end of the month.^[215][217] On the southern front, Hamam al-Alil was fully captured by pro-government forces, after two days of clearing out the remaining ISIL fighters.^[218] In eastern Mosul, the ISOF surrounded the neighborhoods of Karama, Malayyin al-Salasa, Shquq Khazraa, Zahra, Karkuli, Aden and Zahabi.

Following the end of the Tal Afar offensive, the Iraqi Army launched another offensive to retake the ISIL-controlled Hawija Pocket on 20 September 2017.^[377]

Up to 1.5 million civilians lived in the city, sparking concerns among various organizations of a large humanitarian crisis.^[378] Lise Grande, the United Nations' humanitarian coordinator in Iraq, stated, "In a worst-case scenario, we're literally looking at the single largest humanitarian operation in the world in 2016."^[378] Save the Children warned that massive civilian bloodshed was likely, unless safe routes were authorized to let civilians flee.^[379] The U.S. government has accused ISIL of using civilians as human shields.^[380]

Fears that civilians could be used as human shields by ISIL were realized as it was confirmed the group had been abducting civilians from villages for this purpose, which received widespread condemnation from human rights groups and the United Nations Security Council.^[381][382]

Shortly after the battle began, news surfaced of ISIL kidnapping and executing civilians in Mosul. Pentagon spokesman Capt. Jeff Davis stated that ISIL was using civilians as human shields and holding people against their will in the city.^[383]

The International Business Times reported that ISIL has forced boys from Mosul as young as 12 to fight for them, and that ISIL had trained the children to "behead prisoners and make suicide bombs."^[384]

On 17 March, a U.S.-led coalition airstrike in Mosul killed more than 200 civilians.^[391][392] Amnesty International's senior investigator on crisis response said: "The high civilian toll suggests that coalition forces leading the offensive in Mosul have failed to take adequate precautions to prevent civilian deaths, in flagrant violation of international humanitarian law."^[393]

An estimate in mid-July 2017 by Kurdish intelligence put the total number of civilian casualties at 40,000. The largest portion of this loss of life is attributable to the unyielding artillery bombardment by Iraqi government forces—in particular, units of the Iraqi Federal Police—of west Mosul. Killings by ISIL and air strikes were two other significant sources of civilian deaths.^[394]

The World Health Organization stated on 4 March 2017 that twelve people were being treated in Erbil for possible exposure to chemical weapons in Mosul.

According to the UN, four patients show "severe signs associated with exposure to a blister agent", which they were exposed to on the eastern side of the city.^[395][396]

In April 2017, American and Australian advisory forces embedded with Iraqi units were attacked with low-grade, "rudimentary" chemical weapons during an offensive.^[397]

Italian Filippo Grandi, the UN High Commissioner for Refugees, arrived in Erbil on 17 October to meet with Kurdish officials.^[398] The UN has set up five refugee camps capable of taking up to 45,000 people and has the capability of taking in up to 120,000 if more sites are available for camps.^[399] Dozens of families from Mosul arrived in the Al-Hawl camp in Rojava, northern Syria, bringing the number of Iraqis in al-Hawl to more than 6,000. On 18 October, more than 2,000 refugees from Mosul were attempting to cross into Syria, according to the People's Defense Units (YPG).^[138] The UN is attempting to communicate with citizens inside Mosul that they should not flee to the West of the city toward Syria, an area still under ISIL control, but to the camps in the east.^[400]

The World Health Organization (WHO) said it had trained 90 Iraqi medics in "mass casualty management" as part of its preparations for the Mosul operation, with a special focus on responding to chemical attacks, AP reported. ISIL has previously used chemical weapons in attacks on Iraqi and coalition forces, and there are fears that it might do so again inside Mosul, where more than a million civilians live.^[180]

On 3 November, Kurdish and UN aid workers said that more than 40,000 refugees had fled to Kurdistan in the first few weeks of fighting. Ten new refugee camps have been built in the Dohuk Governorate, Erbil Governorate and in the town of Khazir.^[401] According to the United Nations and UNICEF, 22,000 people had been displaced, including more than 9,000 children.^[402]

On 6 November, the United Nations High Commissioner for Refugees (UNHCR) stated that 33,996 people had been displaced from the Mosul District. Sixty-three percent of families are missing civil documentation and 21 percent of families are headed by a female. The previous 48 hours saw a 53 percent increase in displacement.^[56] The following day, WHO announced it had established 82 "rapid response teams" to prepare for possible concerns among civilians fleeing Mosul, including health epidemics such as cholera, and exposure to chemicals and smoke from burning oil wells.^[403] A particular concern is potential disease outbreaks among young children who have not been immunized since ISIL took over the city in June 2014.^[404]

More than 900 Iraqi civilians have fled to the Al-Hawl refugee camp located in the Rojava region of northeastern Syria, while another 700 civilians have migrated to the Turkish–Iraqi borders.^[405]

In March 2017, the WHO contracted Australian health services company Aspen Medical to manage a 48-bed field hospital south of Mosul.^[406] Aspen Medical initially provided a team of over 80 clinical, project management, logistics and support personnel.^[407] By June, the company was managing an additional hospital.^[408]

 United States

• President Barack Obama said on 18 October, "Mosul will be a difficult fight and there will be advances and setbacks. I am confident, just as ISIL has been defeated in communities across Iraq, ISIL will be defeated in Mosul as well, and that will be another step toward their ultimate destruction."
• Secretary of Defense Ashton Carter said on 16 October, in a statement,^[416] "This is a decisive moment in the campaign to deliver ISIL a lasting defeat."^[417]

Iraqi Baath Party

• Secretary General of the Iraqi Baath Party and former vice-chairman of the Iraqi Revolutionary Command Council and current leader of the Army of the Men of the Naqshbandi Order, Izzat Ibrahim al-Douri released a statement in early 2018 commemorating the anniversary of the Baath Party's foundation, in the statement he condemned the Iraqi Government and the military action taken in Iraq against ISIL calling on "Baathist Youth" to continue to rebel against the Iraqi Government, he also referred to Iranian forces and allied paramilitary groups as Safavids. Douri also stated he had great hope in Saudi Arabia to help Iraq against Iran's influence, in the statement Douri said that Iraqi Prime Minister Haider al-Abadi personally destroyed Tikrit, Mosul, Fallujah and other Sunni majority cities in northern Iraq as part of their war against ISIL and that the Badr Organization was directly under Iranian control. He also threatened to go to war with the Iraqi government and allied Shiite militias.^[418][419]

Several media outlets including Al Jazeera and Channel 4 live streamed the first day's battle on Facebook, a first in war coverage.^{[420][421][422]} Additional live video feeds were available on YouTube and the streaming app Periscope. Iraqi and Kurdish officials are also joining in on social media using the hashtag #FreeMosul.^[423] Brendan Gauthier, assistant editor of Salon, noted that given ISIL's slick campaigns on social media, "It's only appropriate then that the Iraqi military's effort to reclaim Mosul from the PR machine turned extremist group be live-streamed."^[424]

On 17 October, several Iraqi media outlets established the National Media Alliance to support journalists reporting on the battle. The groups include both government-run and private media, including Al Iraqiya and Al Sumaria. The alliance provides technical and journalistic services, including a joint operations newsroom. It was formed to counter ISIL propaganda and foster cooperation among the various media groups in order to reduce chaos and improve safety. Journalist Walid al-Tai told Al-Monitor, "One of the reasons behind the establishment of the alliance is to avoid any chaotic media coverage of the battle as every media and military institution is sending its correspondents to battlefronts. This leads to conflict in the coverage of the fighting and a greater number of casualties among journalists."^[425]

Journalist Mustafa Habib reported that Iraqi citizens are coordinating efforts on Facebook and Twitter to counter ISIL propaganda, such as fake photos and videos, that may be used to intimidate locals in Mosul. A communications department of a Shia militia also announced it would be contributing to a social media campaign, and that 500 Iraqi journalists were embedded with the militias surrounding Mosul to report updates.^[426]

On 27 October 2016, The New Yorker's Robin Wright interviewed the anonymous self-described historian Mosul Eye, a purported Mosuli who has blogged from the city about life in Mosul under ISIL despite death threats from the group. Responding to Wright's questions, Mosul Eye estimated the size and make-up of ISIL's force in Mosul, hopes for the future ("gain back power over the city" with help of "an international trusteeship to protect Mosul"), and the level of support for ISIL inside Mosul ("There is no support for ISIL in Mosul. They are left only with weapons that they will use to kill themselves once the liberating forces make the decision to raid the city.").^[104]

The involvement of Turkey in the operation has considerably strained its relations with Iraq.^[5] Turkey has 1,500 to 2,000 soldiers in Iraq,^[427] including 500 Turkish soldiers deployed to a base near Bashiqa, where they trained 1,500 Iraqi Sunni volunteers, mainly Turkmens, and Arabs to recapture Mosul from ISIL.^[428][429] Turkey's participation is against the wishes of the Iraqi government, which has said the Turks are violating Iraq's sovereignty. Turkey has refused to withdraw its forces.^[5] Turkish President Recep Tayyip Erdoğan told the Turkish parliament on 1 October, "We will play a role in the Mosul liberation operation and no one can prevent us from participating,"^[430] and said their presence was to ensure that Mosul did not fall to Kurdish or Shia control and become a threat to Turkey.^[431][432] Turkey's presence was criticized by Kurds in northern Iraq,^[433] and thousands of protestors demonstrated at the Turkish Embassy in Baghdad on 18 October, demanding Turkish forces withdraw from Iraq.^[434] The United States has reportedly attempted to persuade Iraq to cooperate with Turkey on the Mosul offensive.^[435] Al-Abadi declined the offer of Turkish assistance, saying, "I know that the Turks want to participate. We tell them thank you, this is something the Iraqis will handle and the Iraqis will liberate Mosul and the rest of the territories."^[436] However, on 23 October, Turkish Prime Minister Binali Yıldırım announced Turkish troops had fired on ISIL positions near Mosul after requests for assistance from the Peshmerga.^[5]

The situation between Turkey and Iraq escalated on 1 November, the day Iraqi forces entered Mosul. Turkey announced it was sending tanks and artillery from Ankara to Silopi near the Iraqi border. Turkey's Minister of Defense Fikri Işık said the deployment was a move to "prepare for "important developments" in the region and be ready for any possible scenario" and stated that "further action can be taken if Turkey's red lines are crossed" warning Shi'ite militias and PKK not to "terrorize" and take hold of Iraqi Turkmen-majority regions in the area.^{[437][438][439]} Prime Minister Al-Abadi warned Turkey not to "invade" Iraq, predicting war if they did. Al-Abadi, addressing journalists in Baghdad, said, "We warn Turkey if they want to enter Iraq, they will end up becoming fragmented... We do not want to fight Turkey. We do not want a confrontation with Turkey. God forbid, even if we engage in war with them, the Turks will pay a heavy price. They will be damaged. Yes, we too will be damaged, but whenever a country fights a neighboring country, there will be no winner, both will end up losing."^[440]

On 7 November, Iraq rejected Turkey's proposal to continue running the Bashiqa military camp, no matter if it were formally transferred under the auspices of the coalition forces, and suggested that Turkey hand over control of the camp to Iraq's central government.^[441]

In February 2017, Human Rights Watch issued a report regarding the violation of the laws of war in Iraq. According to the report, Islamic State fighters occupied Al-Salam Hospital in Mosul in June 2014, and put the staff and the patients at risk of attacks. During the Battle of Mosul, seven Iraqi soldiers' corpses were dragged through the streets, and the bodies of three soldiers were hanged from a bridge in the city. As the report mentioned, ISIL fighters occupied a clinic in the town of Hammam al-Alil, which was then hit by an airstrike without warning on 18 October, killing at least eight civilians. Previously, they occupied other clinics in other towns controlled by the Islamic State fighters in Iraq, as well operating offices in all the medical facilities in the Republican, Ibn Sina, al-Salam, and Mosul General Hospitals.

Human Rights Watch has also accused the Iraqi security forces and Popular Mobilization Forces (PMF) of dragging the bodies of alleged ISIL fighters in the town of Qayyarah and in the city of Fallujah, after Iraqi forces took eastern Mosul on 24 January 2017.^[442] They warned that allowing PMF to conduct the screenings of men and boys fleeing Mosul for having fought for ISIL would have "dire human rights consequences."^[443]

Human Rights Watch warned that PMF were poorly trained to conduct these screenings. They argued that the irregular nature of screening and detention practices and isolation of detainees in custody risk abuse of the detainees, including arbitrary detention and enforced disappearances. Despite assurances from the Iraqi government that the PMF would not screen detainees in Mosul, an observer reported that three PMF groups were seen at a screening site on 11 March 2017: Hezbollah Brigades, al-Abbas Brigades and Imam Ali Battalions.^[443]

On 11 July 2017, a report was published by Amnesty International, accusing both sides of violating international laws in the battle, about a day after victory was declared by Iraqi forces. The report accused Iraqi forces and the US-led Coalition of carrying out a series of unlawful attacks in west Mosul, relying heavily on Improvised Rocket-Assisted Munitions (IRAMs), explosive weapons and the failure of government to take necessary precautions to prevent the loss of civilian lives and in some cases including disproportionate attacks.^[444]

According to a report published by UN Assistance Mission for Iraq and the Office of the UN High Commissioner for Human Rights in November 2017, at least 2,521 civilians were killed in the battle, mostly because of ISIL including executions of at least 741. It also recorded 461 civilian deaths in airstrikes during the most intensive phase from 19 February. It noted that ISIL had announced in November 2016 that civilians under government-held areas would be considered "legitimate targets" as they didn't fight the pro-government forces. It also called upon Iraqi authorities to investigate alleged violations and human rights abuses by Iraqi security forces during the battle.^[445]

An Associated Press investigation that cross-referenced independent databases from non-governmental organizations, claimed that 9,000–11,000 residents of Mosul were killed in the battle. It blamed airstrikes and shellings by Iraqi forces and anti-ISIL coalition of being responsible for at least 3,200 civilian deaths. The coalition on the other hand has acknowledged responsibility for 326 deaths. ISIL was held responsible for killing one third of the civilians out of the death toll. AP also obtained a list of 9,606 people killed in the battle from Mosul's morgue while Iraqi Prime Minister Haider al-Abadi had claimed 1,260 deaths. Four thousand two hundred were confirmed to be civilians. Names of ISIL fighters and casualties from outside Mosul were discarded by the investigation. It stated, however, that some ISIL members might be among the remaining 6,000.^[446]
