SINJAR, IRAQ - NOVEMBER 15: Former Yazidi resident Khalaf Halti, 62, walks through the rubble of his neighborhood on November 15, 2015 in Sinjar, Iraq. Kurdish forces, with the aid of massive U.S.-led coalition airstrikes, liberated the town from ISIL extremists, known in Arabic as Daesh, in recent days. Although many minority Yazidis celebrated the victory, their home city of Sinjar lay in almost complete ruins. Yazidi fighters and some former residents have been taking any salvagable items out of the rubble, the town being uninhabitable and perilously close to the frontline.
