ISIS attacked a battalion of state-sponsored militia southeast of Tikrit on Friday, killing at least eight militia members, an intelligence official said.
ISIS claimed responsibility for the attack in a statement posted by its Aamaq news agency. The statement said ISIS fighters had struck the 9th Battalion of the Popular Mobilization Forces, "killing its commander and 13 soldiers."
The statement also said that ISIS fighters blew up the battalion's headquarters and other nearby positions and destroyed two Humvees that had arrived to assist the battalion.
