A picture taken on August 10, 2014 shows Yazidi Iraqi fighters walking past the grave of a child who died of malnutrition at a cemetery in the Kurdish city of Dohuk in Iraq's autonomous Kurdistan region, where Yazidi families took refuge after they fled the Mount Sinjar area. Thousands of Yazidis, a Kurdish-speaking minority following an ancient faith rooted in Zoroastrianism, fled their homes a week ago when Islamic State (IS) militants attacked the town of Sinjar.
