ERBIL, IRAQ - DECEMBER 08: An Iraqi Christian boy, who fled from his home because of Islamic State's advance earlier this year, sits at the wheel of a car at the entrance to a camp near Umm al-Nour Church, which is now home to hundreds of displaced Iraqi Christians on December 8, 2014 in Erbil, Iraq. Although the autonomous Kurdistan region in northern Iraq was already a refuge for an estimated 250,000 Syrian refugees, since the Islamic State began its onslaught on Iraq in June, Kurdistan has also taken in a more than one and a half million displaced people. Many have been placed in purpose-built refugee camps but the huge numbers mean thousands of others are forced to live in un-finished buildings or inadequate, makeshift shelters and as winter in the region closes in, there are growing concerns for the welfare of the refugees who, while their homes are still in ISIL controlled territory, have no realistic prospect of returning to them.
