Eight policemen were killed in a bank robbery in central Baghdad early on Tuesday, in which the robbers made off with the equivalent of about 5.7 million dollars, according to a government official.

Seven Iraqis were killed and at least 15 were wounded Wednesday when a man detonated explosives packed in his car in central Ramadi, west of Baghdad, police said.

"A suicide bomber blew up his car," police spokesman for al-Anbar Province Rahim Zubn told Baghdad's Aswat al-Iraq news agency.

Two suicide bombers left 15 people dead and more than 40 injured on Thursday in the northern Iraqi city of Mosul, police sources told the German Press Agency dpa.

The bombers detonated their explosives in a crowded street in Tel district, where many Shiite Turkmen congregate, sources added.

Two civilians were killed on Monday and ten more injured in Baghdad when a bomb exploded near a vegetable market, an interior ministry source said.

The source told Aswat al-Iraq news agency that the explosion took place in Alwat al-Rasheed market, southern Baghdad.

On May 6 a car bomb went off at the same market killing 12 and injuring another 44.

A man killed 33 people and himself when he detonated explosives strapped to his body in a crowd queuing up for humanitarian aid in central Baghdad Thursday, police said. At least 57 people were wounded in the attack, police told the German Press Agency dpa. It was unclear who was responsible.

The news came as members of an Awakening Council, a government- allied, Sunni militia enlisted to patrol Abu Ghraib, west of Baghdad, left their posts on Thursday, following their leader's resignation.

At least 10 people were killed Monday and 45 were injured as four bombs rocked separate locations in Baghdad, television reports said.

Iraq's al-Iraqia channel said four were killed and 15 were injured in a blast in the bustling al-Alawi commercial district in central Baghdad.

Two further bombings occurred in Shiite-dominated suburbs, while the fourth attack involved a car bomb in al-Naria district, in south- eastern Baghdad, targeting an official of the Interior Ministry.

Two simultaneous explosions killed nine policemen on Sunday in Anbar province west of Baghdad, police said.

A police source told the German Press Agency dpa that the bombs ripped though a patrol in Faluja, 70 kilometres west of Baghdad, killing an officer and eight other policemen.

The Iraqi security forces took over security responsibility for the Sunni-dominated Anbar province in September 2008 from the US-led Multi-National Force in Iraq.

Iraqis were going to the polls on Saturday in the biggest elections in the country's history as receding violence created conditions far more secure than the last elections in 2005.

Some 14,400 candidates were contesting 440 provincial seats, creating fierce competition among candidates that is expected to lead to greater representation of the country's sects.

Sunnis who boycotted the last elections, delivering disproportionate representation for Kurds and Shiites, are now competing for more seats.
