Haunting Photos Of Iraqi Minorities On The Run From The Islamic State

As Islamic State fighters extended their offensive into northern Iraq on Thursday, members of Iraq's minority communities fled in search of refuge. The militant group has warned that it would execute anyone who does not convert to Islam, pay a non-Muslim tax or leave, according to Human Rights Watch.

Thousands of Yazidis -- a Kurdish ethno-religious community -- have been trapped on Sinjar Mountain in northern Iraq as they attempt to escape the extremists' grasp. The sole parliamentary representative of the Yazidis, Vian Dakhil, warned that her small community, which has roots in a 4,000 year-old faith, faces the threat of extermination.

Other religious and ethnic groups, including Christians, Shiite Turkmens and Shabaks, have also recently been displaced since the Islamic State began waging a violent campaign against minorities in the territory it controls.
