Newly displaced Iraqi's who fled from the city of Mosul, Iraq's last major Islamic State (IS) group stronghold, are reunited with their relatives who came two years ago to the refugee camp in the Khazer area, near near the Kurdish checkpoint of Aksi Kalak, some 40 kilometres east of Arbil following their arrival on October 26, 2016. The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) Stephane Dujarric told reporters that almost 9,000 people are internally displaced as a result of the Mosul military operation in Iraq. Lise Grande, the U.N. humanitarian coordinator for Iraq, said the military operations to retake Mosul could spark the largest humanitarian crisis in 2016 as the security situation in the area restrains aid agencies' ability to deliver help.

A girl holds her brother in her arm as black smoke rises after an oil well set on fire in the center of al-Kayyara town to the south of Daesh terror organization-held Mosul in Iraq on October 25, 2016. The oil well in the center of al-Kayyara town, which was set alight by retreating Daesh militants in advance of the Iraqi army's takeover of the town on August 24, 2016 has still not entirely been put out. The raw petrol which is still alight is creating black clouds above the city. The residents and wildlife beneath this polluting smoke cloud may find their health at risk. The effects of the fire in the town center on unprotected civilians' health can easily be seen on the hands and faces of children playing on the street.

Iraqi forces battled Islamic State fighters for a third day in a remote western town far from Mosul on Tuesday, but the U.S.-led coalition insisted the latest in a series of “spoiler attacks” had not forced it to divert resources from the fight to retake Iraq's second-largest city.

Iraqi forces flash the V-sign as they stand on an infantry fighting vehicle loaded on a truck driving through the Al-Shura area, south of Mosul, on October 24, 2016, during an operation to retake the main hub city from the Islamic State (IS) group jihadists. Iraqi forces advancing on Mosul faced stiff resistance from the Islamic State group on October 24 despite the US-led coalition unleashing an unprecedented wave of air strikes to support the week-old offensive. Federal forces and Kurdish peshmerga fighters were moving forward in several areas, AFP correspondents on various fronts said, but the jihadists were hitting back with shelling, sniper fire, suicide car bombs and booby traps.

An Iraqi Federal Police vehicle passes through a checkpoint in Qayara, some 50 kilometers south of Mosul, Iraq, Wednesday, October 26, 2016. Islamic State militants have been going door to door in farming communities south of Mosul, ordering people at gunpoint to follow them north into the city and apparently using them as human shields as they retreat from Iraqi forces. Witnesses to the forced evacuation describe scenes of chaos as hundreds of people were driven north across the Ninevah plains and into the heavily-fortified city, where the extremists are believed to be preparing for a climactic showdown.
