In a new report, Amnesty International says Shi’ite militias in Iraq have "abducted and killed scores" of Sunni Muslim civilians in recent months and enjoyed "total impunity" for these "war crimes."
The report, published on October 14 and entitled "Absolute Impunity: Militia Rule in Iraq," is based on interviews conducted in August and September.
It provides details of what Amnesty says were sectarian attacks carried out by militia members in the cities of Baghdad, Samarra, and Kirkuk.
The London-based group said scores of unidentified bodies have been found, many still handcuffed and with gunshot wounds to the head, suggesting execution-style killings.
It said many others who disappeared remain unaccounted for.
Amnesty said the killings were in apparent revenge for attacks by Islamic State militants.
It said the "increasingly powerful" Shi’ite militias were "supported and armed" by Iraq's government.
