A series of car bombs exploded in Shiite areas of Baghdad Tuesday, killing at least nine people and injuring more than 60, an interior ministry official said.
Two of the bombs exploded within half an hour of each other in the capital's Sadr City Shiite bastion, killing six people and wounding 32, the official said.
The first bomb ripped through a group of workers at around 6:45 am (0345 GMT) while the second exploded outside a bakery. Among the wounded were two women and a child.
A third car bomb exploded in Shula, a northwestern district of the capital, killing two people and wounding 16, while a fourth killed one person and wounded 13 in the northern neighbourhood of Al-Hurriya, the official said.
The bombings are the latest in a spate of attacks against Shiites, which have risen since US forces completed their withdrawal from Iraq on December 18.
Though violence in Iraq is down markedly from its peak during 2006 and 2007, attacks are still common, and more than 200 people have been killed since the US drawdown.
