DOHUK, IRAQ - AUGUST 16: Yezidis who fled their home due to the assaults of army groups led by Islamic State (IS), formerly known as ISIL, take shelter in the buildings under construction in Zakho district, a few kilometers from the Iraqi-Turkish border, Dohuk on August 16, 2014. Islamic State fighters captured Iraq's Sinjar and Rabia in the Nineveh province last week after fierce clashes, forcing thousands of Iraqis including Turkmen, Arabs and Yezidis to flee.
