Iraqi officials say a roadside bomb targeting a security patrol has killed two policeman in the western province of Anbar.

An Iraqi policeman says the blast Saturday morning also wounded a policeman and destroyed a police vehicle in Khaldiyah, 90 kilometers (55 miles) west of Baghdad. A medic at nearby al-Ramadi general hospital confirmed the casualties.

Both officials spoke on condition of anonymity because they were not authorized to release the information.

Insurgents often launch attacks against security forces in an attempt to undermine Iraq government.
