Suicide bomb attacks on a western Iraq police station killed at least five policemen and wounded about 15 more people on Thursday, an unidentified provincial police source told Reuters.
The attacks are just the latest in a string of deadly incidents that have rocked the country, and while no group has claimed responsibility, suicide bombings have been linked before to al Qaeda's the Islamic State of Iraq insurgents.
Twin suicide bombers detonated themselves at a checkpoint entrance to the police station in Anbar, according to Xinhua news agency, which also reported at least seven people had been killed.
China's state-run paper also mentioned a third assailant who died while driving a vehicle full of explosives into the police station.
Since June more then 1,000 people have died in Iraq militant attacks, and more than 2,500 have died in violent attacks since April, according to the United Nations. That means Iraq is suffering one of its worst strings of sectarian violence in several years.
