More Iraq Flareups

Dozens killed in day of attacks across Iraq

Mortar fire slammed into a marketplace in Baghdad̢۪s biggest Shiite Muslim neighborhood, and a roadside bomb hit a bus Saturday, a day that saw at least 33 Iraqis killed in multiple attacks. Outside Baghdad, insurgents rocketed a U.S. military base, killing four soldiers.

In Sadr City, the capital̢۪s sprawling Shiite slum, angry residents vented anger at Iraq̢۪s U.S. occupiers after the mortar barrages, which followed an early morning clash in the neighborhood between U.S. troops and militiamen loyal to a radical Shiite cleric.

The worst single incident of the day came when a bomb exploded on a main road as a bus passed near Haswa, 30 miles south of Baghdad. The back of the bus was shredded and seats crumpled. At least 13 people — including a four-year-old boy — were killed and 17 wounded, said Wasan Nasser, a doctor at Iskan Hospital in neighboring Iskandariyah.
