BAGHDAD, April 30 (Xinhua) -- Four people were killed and 25 other wounded in bomb attacks in Baghdad on Monday afternoon, an Interior Ministry source said.

    A car bomb went off shortly before 5:00 p.m. (1300 GMT) in a commercial area in Baghdad's southern district of Baiyaa, killing two people and wounding eight others, the source told Xinhua on condition of anonymity.

    The blast also damaged several nearby buildings and shops while ambulances and fire engines rushed to the scene, he said.

    Earlier, another car bomb detonated near an Iraqi army patrol in the Rabie Street in the Jamiaa district in western Baghdad, wounding four civilians, the source added.

    Meanwhile, a civilian was killed and nine others were wounded when several mortar rounds landed near a mosque in the Shaab neighborhood in northeastern Baghdad, the source said.

    Separately, a civilian was killed and four others were wounded when a roadside bomb went off in the Talbiyah neighborhood in northern Baghdad, the source said.

    Violence persists in Baghdad and other Iraqi areas despite the presence of tens of thousands of U.S. and Iraqi soldiers across the country in a major security crackdown aimed at curbing insurgency and sectarian violence.
