At least six people were killed and dozens injured in a number of bomb attacks, including car bombs, while three US troops were killed on Sunday and Monday in separate roadside bombings.
Three people were killed and five wounded when a suicide car bomber attacked a police patrol outside the Iranian embassy in Baghdad, an interior ministry official said.
One Iraqi policeman was also killed and four more wounded in a southwest Baghdad car bomb attack, while two more policemen were wounded by a roadside bomb in the north of the capital.
Suicide bomb
Separately police reported a suicide bombing attack on a joint US-Iraqi checkpoint in the west of the capital. There was no word on casualties.
Naji Ithawi, an official working for the Sunni religious endowment foundation, was also shot dead while leaving a mosque in southwest Baghdad after evening prayers, according to Medhi Meshadani, a spokesman for the foundation.
A woman working as a cleaner at a US base was shot dead in Al-Dawr, near Saddam's hometown of Tikrit.
Four civilians were wounded in a car bomb attack near a court house in Mahmudiyah, south of Baghdad, and five policemen hurt in a bomb attack in the northern city of Kirkuk, police said.
Two US airmen and one soldier were killed Sunday and Monday in Iraq, taking to at least 2,237 the number of US military personnel who have died in the country since the March 2003 invasion, according to Pentagon figures.
Iraqi authorities announced they have recovered eight more bodies in an area north of Baghdad where on Sunday they found those of 23 police volunteers who had been shot dead after being seized by insurgents a week earlier as they travelled home by bus.
Saddam’s trial to resume
The wave of attacks came less than 24 hours before Saddam Hussein’s trial resumed after a month-long recess.
The court's investigating judge Raed al-Juhi said a previously unknown magistrate, Rauf Rashid Abdel Rahman, would temporarily take over as presiding judge.
This followed the resignation of Rizkar Mohammed Amin who quit because of strong criticism over allowing the defendants to grandstand.
Abdel Rahman was born in Halabja, the Kurdish town which became a symbol of repression in 1988 when Saddam's forces used chemical weapons against its inhabitants, killing some 5,000.
"He will remain as presiding judge until such a time as an official decision is taken on whether to accept judge Rizkar's resignation," Judge Juhi said.
It will be up to the government to accept Judge Amin's resignation and for the five-judge panel to elect his successor.
Saddam and seven co-defendants face death by hanging if convicted of mass killings of Shiite residents from the town of Dujail, where Saddam escaped a plot to kill him in 1982.
