Police: 65 dead in Iraq mosque shooting At least 21 dead in suicide bombing
Victims of the massacre “by Iraqi pro-government militias and security forces recognized the attackers and knew them by name,” the report said. Some wore Iraqi police uniforms, according to the report.

The rights group called on the government to make public details of its findings into the attack, which HRW said was consistent with a pattern of killings being carried out in Iraq by Shiite militias, including al Haq, the Badr Brigades and Kataib Hezbollah.

“Pro-government militias are becoming emboldened and their crimes more shocking,” said Joe Stork, deputy Middle East director at HRW.

“Iraqi authorities and Iraq’s allies alike have ignored this horrific attack and then they wonder why the militant group Islamic State has had such appeal among Sunni communities.”
