Gunmen disguised as police raided checkpoints and homes in western Iraq on Monday, killing at least 27 members of the security forces, police said, in an attack the authorities said bore the hallmarks of al Qaeda. The attacks in Anbar, once Iraq's most violent province, raise concern that Iraq's branch of al Qaeda may regain a foothold there after the withdrawal of US troops in December.
Anbar was almost entirely under control of al Qaeda during the height of Iraq's insurgency from 2005-07, when the militants were defeated by local tribesmen and US forces. A police source, who had been ferrying victims to the hospital morgue, said gunmen dressed in uniforms of the security forces had driven from checkpoint to checkpoint slaughtering police in Haditha, a town 190 km (120 miles) north-west of Baghdad.
