4 bombings kill at least 127 in Baghdad

Four large bombs exploded across Baghdad today, killing at least 127 people and wounding scores as violence climbed toward levels seen before the U.S.-Iraqi campaign to pacify the capital began two months ago.

In the deadliest of the attacks, a parked car bomb detonated in a crowd of workers at the Sadriyah market in central Baghdad, killing at least 82 people and wounding 94….

Among the dead were several construction workers who had been rebuilding the mostly Shiite marketplace after a bombing destroyed many shops and killed 137 people there in February, the police official said.

The market is situated on a side street lined with shops and vendors selling produce, meat and other staples. It is also about 500 yards from a Sunni shrine.

About an hour earlier, a suicide car bomber crashed into an Iraqi police checkpoint at an entrance to Sadr City, the capital’s biggest Shiite Muslim neighborhood and a stronghold for the militia led by radical anti-U.S. cleric Muqtada al-Sadr.

The explosion killed at least 30 people, including five Iraqi security officers, and wounded 45, police said.

Black smoke billowed from a jumble of at least eight incinerated vehicles that were in a jam of cars stopped at the checkpoint. Bystanders scrambled over twisted metal to drag victims from the smoldering wreckage as Iraqi guards staggered around stunned.

Earlier, a parked car exploded near a private hospital in the central neighborhood of Karradah, killing 11 people and wounding 13, police said. The blast damaged the Abdul-Majid hospital and other nearby buildings.

The fourth explosion was from a bomb left on a minibus in the northwestern Risafi area, killing four people and wounding six others, police said.

Also in Baghdad, four policemen were killed this afternoon when gunmen ambushed their patrol south of the city center, police said. Six pedestrians were wounded in the gunfire.

U.S. officials had cited a slight decrease in sectarian killings in Baghdad since the U.S.-Iraqi crackdown was launched Feb. 14. But the past week has seen several spectacular attacks on the capital, including a suicide bombing inside parliament and a powerful blast that collapsed a landmark bridge across the Tigris River.
