ISIS kills 27 pro-Iraqi government fighters in ambush

(OAN) — ISIS militants claimed responsibility for killing more than 25 pro-government fighters in an ambush attack in northern Iraq.

The assault happened north of Baghdad on Sunday evening when Shiite militia forces were conducting overnight raids.

The militants were reportedly disguised in military uniforms, and operated fake checkpoints before clashing with Iraqi forces for at least two hours.

Officials say troops were killed at the scene, including some who were beheaded.

A leader from one of the most prominent Shiite militias vowed revenge, and called on security forces to be vigilant.
