BAGHDAD - A car bomb explosion killed four people and wounded 25 others in a predominantly Shi'ite area of southern Baghdad on Tuesday, an Interior Ministry source said.
The bomb blew up near a market and bakery in Baghdad's Abu Dsheer district, the source said.
A police source put the toll at four dead and 24 wounded.
"It was a bomb inside a vehicle which resulted in the death and injury of a number of civilians in the district of Abu Dsheer," said Major-General Qassim al-Moussawi, Baghdad's security spokesman. He declined to give a casualty toll. Iraqi security forces went on high alert on Monday after US forces killed al-Qaida leader Osama bin Laden. Officials said they expected al-Qaida's local affiliate to carry out revenge attacks.
