Al Qayyara, south of Mosul. A black smoke rises from the oil well cements. There are still people in the area. A white flag is put on the car by civilians that have to be controlled by the Iraqi Army in order to check if they were members of IS.
Mosul, Iraq's second-most populous city, fell to an ISIL blitzkrieg in June 2014. The group's fighters poured over the border from Syria, seizing large swaths of northern Iraq. Two years later, the Iraqi army - backed by local militias, Kurdish forces and air strikes carried out by an international coalition - began an operation to drive ISIL out of the city.
