KALAK, IRAQ - JUNE 13: Children play in a field at sunset next to a temporary displacement camp set up next to a Kurdish checkpoint on June 13, 2014 in Kalak, Iraq. Thousands of people have fled Iraq's second city of Mosul after it was overrun by ISIS (Islamic State of Iraq and Syria) militants. Many have been temporarily housed at various IDP (internally displaced persons) camps around the region including the area close to Erbil, as they hope to enter the safety of the nearby Kurdish region.
