ROLE OF TRIBES when IS rounded up the remaining civilian population of 1,500 families in Zuwayrah following its capture of the village. A string of mass executions followed. The executions began on 29 October when IS militants paraded more than forty captured Albu Nimr fighters through the streets of Hit—and then shot and killed them in the city’s central square in front of residents.2 The following day, IS publicly executed another seventy-five Albu Nimr tribesmen, forcing dozens of residents to watch as they shot the captives in their heads.3 On 1 November, the jihadist group executed approximately fifty civilians in Ras al-Maa, while thirty-five bodies were found in a mass grave in Hit.4 On 2 November, IS publicly executed fifty Albu Nimr tribesmen in Hit and killed sixty-seven more tribe members as they fled from the village of al-Tharthar.5 On 3 November, IS publicly executed thirty-six Albu Nimr civilians, including women and children, on the outskirts of Hit.6 On 4 November, IS executed twenty-five more tribesmen, shooting them at close range and dumping their bodies in a well.7 On 9 November, IS executed seventy Albu Nimr tribesmen in Hit District and then executed sixteen more tribe members on 13 November.8 The attempted extermination of the Albu Nimr marked, at the time, IS’s most vicious attack on a Sunni population in Iraq. Overall, IS slaughtered more than seven hundred members of the tribe in less than twenty days. Why did IS commit these massacres? What role do the Sunni tribes play in the current battle for Iraq
