Three bomb attacks in Iraq on Wednesday killed 11 people, including four anti-Qaeda fighters who fell when a suicide bomber struck as they gathered to collect their salaries, officials said.

The bomber, who was on foot, detonated explosives at a police station in Fallujah, west of Baghdad, as the Sahwa members gathered near the station, police Lieutenant Colonel Khaled Yassir al-Jumaili said.

The blast killed five people, including a senior police officer and four Sahwa fighters. It also wounded 15 other people.

Near Ramadi, which is also located in Iraq's restive Anbar province, a car bomb killed three police, including an officer, police Captain Marwan al-Dulaimi and a doctor said.

And in Baghdad, a car bomb in the capital's Al-Husseiniyah area killed three people and wounded another 10, officials said.

Wednesday's attacks came after a wave of violence killed more than 240 people over seven days at the end of April, raising fears of a return to sectarian violence that left tens of thousands dead.

Violence in Iraq has fallen sharply from the peak of the sectarian conflict in 2006 and 2007, but violence remains common, killing more than 450 people in April, according to AFP figures gathered from security and medical officials.
