A displaced woman from the minority Yazidi sect, who fled violence in the Iraqi town of Sinjar, worships at their main holy temple in Lalish in Shikhan September 20, 2014. Followers of an ancient religion derived from Zoroastrianism, the Yazidi fled their homeland in the Sinjar mountains as Islamic State militants, who see them as devil worshippers, seized towns and carried out mass killings in August.
