An Iraqi child waits with her family to get into a temporary displacement camp for Iraqis caught-up in the fighting in and around the city of Mosul on June 26, 2014 in Khazair, Iraq. Khazair is now home to an estimated 1,500 internally displaced persons (IDP's) with the number rising daily. Tens of thousands of people have fled Iraq's second largest city of Mosul after it was overrun by ISIS (Islamic State of Iraq and Syria) militants. Many have been temporarily housed at various IDP camps around the region including the area close to Erbil, as they hope to enter the safety of the nearby Kurdish region.
