Gunmen opened fire inside a Sunni mosque in Iraq's eastern Diyala governorate, killing at least 68 people, Aug. 22. A suicide bomber broke into the Musab bin Omair Mosque during Friday prayers in the village of Imam Wais and detonated his explosives. He was followed by gunmen, who rushed in and opened fire on the worshippers. Initial reports blamed ISIS in the massacre, but reports later in the day blamed an unnamed Shi'ite militia, suggesting it was retaliation for a roadside bomb attack at a recruitment event organized by the militia.

Last month, Shi'ite militiamen executed 15 Sunni Muslims and hanged them from electricity poles in a public square in Baquba, Diyala's capital. In the wake of the mosque massacre, two influential Sunni politicians—deputy prime minister Saleh Mutlaq and parliament speaker Salim al-Jibouri—announced they are pulling out of talks on forming a new government until the investigation into the attack is completed.
