The suicide attacker joined a line of people waiting to buy kerosene before detonating the explosives strapped to his body, witnesses said in the eastern New Baghdad neighbourhood. The blast killed 23 people and injured 51, said Interior Ministry official Maj. Falah al-Mohammedawi.

A car bomb targeting a police patrol in the same neighbourhood killed nine people and injured 17 all civilians said police Lt. Alu Abbas and medic Rahim al-Waedi.

Another car bomb exploded near a Shia mosque in the crowded southeastern Karada neighbourhood, killing four people and injuring 16, said al-Mohammedawi.

Police said the vehicle was parked next to a small market opposite the Timimi mosque, which was closed for repairs. But witnesses said the vehicle was driven by a suicide attacker.

Distraught residents rushed to the scene, as fire fighters fought back flames from burning cars.

A roadside bomb targeting the convoy of a defence ministry adviser killed five soldiers and injured seven others, ministry spokesman Mohammed al-Askari said. The adviser, Lt. Gen. Daham Radhi al-Assal, escaped without harm, he said.

A fifth blast took place in an open area near the downtown national theatre, al-Mohammedawi said. Initial police reports indicated a mortar blast. There were no reports of casualties.

Elsewhere in Iraq, the US military said an American soldier of the Multinational Division-Baghdad was killed by small arms fire Monday west of Baghdad. The death brought to at least 2,292 the number of members of the US military who have died since the beginning of the Iraq war in March 2003, according to an Associated Press count. The figure includes seven military civilians.

Two British soldiers were also killed in Amarah, 180 miles southeast of Baghdad, the Defence Ministry reported in London, but gave no other details. A witness said a car bomb targeted a British patrol and helicopters were seen taking away casualties.

Iraqi soldiers found the bullet-riddled bodies of nine people near two burned minibuses in Iraq's strife-prone Diyala province, police said. The victims included Sheik Hamid Irbat Ghazi, a Sunni Muslim of the influential Mahamdeh tribe, and two of his nephews, police said.

In Tikrit, near Saddam's birthplace north of Baghdad, a bomb blast damaged a dome and blew out the doors and windows at the Hussein al-Majid mosque, which houses his father's grave, police Capt. Qais Abdul-Majid said. There were no reports of injuries.

Sectarian clashes had declined sharply since the bloodletting that followed the destruction of the Shia shrine in Samarra on Wednesday. Baghdad residents had returned to their jobs after three days of a government-imposed curfew.

Turkish Prime Minister Recep Tayyip Erdogan, meeting with Iraqi Prime Minister Ibrahim al-Jaafari in Ankara, called on Iraqi leaders to work together and avoid provocations to defuse the violence that threatens to create unrest in the region.

"The Iraqi issue is of vital importance," Erdogan said. "Turkey fervently wants the environment of conflict and violence to be eliminated and for the common sense to take its place."

Crying relatives, meanwhile, went to Baghdad's main morgue to collect the bodies of family members killed in the spasm of violence in the past week. Many of the mourners were women dressed in black who beat their breasts as they wailed in grief.

One young man, who refused to give his name, told an AP reporter his three brothers had gone out to buy bread Saturday night and were gunned down in a drive-by attack.

So far, officials at the morgue said 249 bodies had been brought to the facility since Wednesday. The Interior Ministry had only confirmed 216 deaths since the shrine attack, but it relies on death certificates from around the country and the process can be slow.

The Washington Post reported Tuesday that more than 1,300 Iraqis had been killed since the shrine attack.

Saddam Hussein's defence lawyers ended their monthlong boycott of his trial, attending proceedings yesterday even though the judge rejected their demands that he step down. Their return gives a boost to a troubled trial.

Saddam's defence team walked out of his trial on Jan. 29 after chief judge Raouf Abdel-Rahman tossed out one of the lawyers for shouting. The defence then said it would boycott the trial unless Abdel-Rahman was removed, accusing him of bias against Saddam. Court-appointed lawyers sat in during sessions over the past month.

Saddam and his seven co-defendants entered the court Tuesday and took their seats silently a rarity since the former Iraqi leader and his half-brother Barzan Ibrahim have shouted slogans or argued with the judge at the start of almost every previous session.

The defendants have been on trial since Oct. 19 in the killing of nearly 150 people from the town of Dujail after a 1982 assassination attempt against Saddam there. They face death by hanging if convicted.
