Islamic State has hounded ethnic and religious minorities in northern Iraq since seizing the city of Mosul in June, killing and displacing thousands of Christians, Shi'ite Shabaks and Turkmen who lived for centuries in one of the most diverse parts of the Middle East. Hundreds of Yazidi women and girls have been captured, raped and tortured, and forced to convert to Islam and marry Islamic State followers, according to rights groups. The Yazidi are a religious sect whose beliefs combine elements of several ancient Middle Eastern religions. Tens of thousands have fled Islamic State fighters, who say the Yazidi must embrace their radical version of Islam or die. Reuters/Ari Jalal
