The al-Hol refugee camp, in northeastern Syria near the border with Iraq, is overwhelmed with new arrivals. For years, the camp, run by Kurdish authorities with help from the United Nations and other international organizations, has housed thousands of Iraqi refugees. More recently, though, the camp has become home to large numbers of Syrians, fleeing towns where the U.S.-led coalition is fighting the last remnants of ISIS. Hundreds of thousands have become internally displaced, with many families forced to move multiple times.
