 ISIL's actions against the Yazidi population have resulted in approximately 500,000 refugees.The Yazidis are monotheists who believe in a benevolent peacock angel and practice an ancient gnostic faith.The self-proclaimed Islamic State of Iraq and the Levant and other followers of Islam in the region tend to view the peacock angel as the malevolent creature Lucifer or Shaitan and they consider the Yazidis 'devil worshippers'.
