BAGHDAD : Gunmen attacked an anti-Qaeda militia checkpoint west of the Iraqi capital on Sunday, killing at least four fighters, security and medical officials said. The attack on a Sahwa militia checkpoint in the Abu Ghraib area also wounded at least three more fighters, the officials said. In Baghdad itself, a roadside bomb exploded in the area, killing at least two people and wounding six, officials said. Violence in Iraq has reached a level not seen since 2008, when the country was just emerging from a brutal period of sectarian killings.

More than 6,750 have been killed in violence since the beginning of 2013, according to AFP figures based on security and medical sources.
