Battle of Mosul (2016–17) The Battle of Mosul (2016–17) was a major military campaign to retake Mosul from the Islamic State of Iraq and the Levant following the group's 2014 capture of the city. The operation involved a coalition of Iraqi Armed Forces, Popular Mobilization Forces, Peshmerga, and international partners including the United States, France, and the United Kingdom. Urban combat, improvised defenses, and the presence of large civilian populations made the offensive one of the largest and bloodiest battles since the Iraq War and a decisive moment in the War against the Islamic State.

Background

In June 2014, Islamic State of Iraq and the Levant forces overran northern Iraq and declared a Caliphate in captured territory, including Mosul and parts of Nineveh Governorate and Anbar Governorate. The fall of Mosul followed the collapse of Iraqi security forces and the strategic withdrawal of Peshmerga and other local defenders, prompting an international response led by the United States Department of Defense and the formation of a Global Coalition to Defeat ISIS. Iraqi Prime Minister Haider al-Abadi announced plans to retake Mosul in 2016, coordinating with Popular Mobilization Forces and advisers from the Islamic Revolutionary Guard Corps and coalition partners.

Forces and Commanders

The assault was conducted by multiple components: the Iraqi Army and Federal Police under the command of the Iraqi Ministry of Defence, counterterrorism units such as the Iraqi Counter-Terrorism Service (ICTS), the Popular Mobilization Forces led in part by Hadi al-Amiri, and the Peshmerga of the Kurdistan Regional Government under leaders like Nechirvan Barzani and Masoud Barzani. International involvement included the United States Armed Forces with advisers from Combined Joint Task Force – Operation Inherent Resolve, air support from the Royal Air Force, French Armed Forces assistance, and intelligence provided by agencies including the Central Intelligence Agency. On the opposing side, Islamic State of Iraq and the Levant leadership, including figures associated with Abu Bakr al-Baghdadi, organized fortified defenses under local wilayat commanders and used tactics drawn from previous engagements in Raqqa and Fallujah.

Course of the Battle

The offensive began on 17 October 2016 with coordinated advances from eastern and southern axes, where Iraqi Army and Federal Police units pushed through suburbs and towns such as Qayyarah and Tal Afar environs. Urban fighting intensified in densely populated neighborhoods, with Iraqi Counter-Terrorism Service spearheading operations into central districts including the Old City and the area around the Grand Mosque of al-Nuri. Islamic State of Iraq and the Levant employed tunnels, improvised explosive devices, suicide bombers, and human shields, echoing tactics used in Second Battle of Fallujah and actions documented in Raqqa campaign (2016–17). The coalition provided close air support, artillery, and reconnaissance, coordinating strikes with forces on the ground; this support was criticized for its impact on infrastructure and civilian areas. Key phases included the capture of eastern Mosul, the encirclement of the western half, and a protracted street-by-street battle for the western neighborhoods. The destruction of the al-Nuri Mosque and the reported death of local IS leaders were pivotal symbolic moments. Iraqi authorities declared victory on 9 July 2017 after clearing remaining resistance and securing municipal structures.

Humanitarian Impact and Civilian Casualties

The battle produced a severe humanitarian crisis across Nineveh Governorate and surrounding regions, prompting responses from United Nations agencies such as UNICEF, United Nations Office for the Coordination of Humanitarian Affairs, and World Food Programme partners. Displacement of civilians led to mass movement toward camps like Hammam al-Alil and Qayyarah Airfield West, straining resources and creating public health concerns documented by World Health Organization teams. Casualty estimates varied; international observers, including representatives of Amnesty International and Human Rights Watch, reported high numbers of civilian deaths, injuries, and missing persons linked to indiscriminate attacks, siege conditions, and explosive ordnance. Reports highlighted shortages of food, water, medical care, and shelter affecting internally displaced persons and returnees.

Aftermath and Reconstruction

Following liberation, authorities from the Iraqi Council of Representatives and the Nineveh Provincial Council faced challenges in restoring services, clearing unexploded ordnance, and rebuilding damaged neighborhoods. International actors including the World Bank, European Union, and bilateral donors such as the United States Agency for International Development and Germany pledged reconstruction assistance and demining support. Efforts involved rehabilitating infrastructure—electricity, water, and hospitals—and re-establishing administrative control amid contested governance between Kurdistan Regional Government institutions and Baghdad-appointed officials. Economic recovery plans referenced reconstruction lessons from Liberation of Mosul (2008)-era operations and contemporary stabilization programs in conflict-affected cities.

War Crimes and Investigations

Allegations of war crimes arose from multiple parties; organizations including Human Rights Watch, Amnesty International, and the International Committee of the Red Cross documented potential violations such as unlawful killings, torture, hostage-taking, and the use of human shields by Islamic State of Iraq and the Levant. Investigations by the Iraqi High Commission for Human Rights, international fact-finding missions, and UN investigative bodies sought accountability for abuses during the offensive. Prosecutions faced obstacles including destroyed records, displaced witnesses, and security constraints. Calls for transitional justice involved references to precedents like International Criminal Court procedures and truth commissions in other post-conflict contexts.
