Mortar barrage and twin roadside bomb attacks in and south of Baghdad on Wednesday killed three people and wounded 24 others, including policemen, a well-informed police source said.
"Mortar rounds landed on a residential area in the Madain town, 30 km south of Baghdad, killing three people and wounding nine others," the source told Xinhua on condition of anonymity.
In eastern of the capital, three policemen were wounded when two roadside bombs detonated in quick succession near a passing police patrol in Zaiyounah neighborhood, the source said.
In addition, the source said that police discovered a booby- trapped truck in downtown Baghdad. Police experts were called in to conduct an under-control explosion, wounding 12 civilians and security members, the source added.
In earlier attacks, another double roadside bombs detonated in the morning near the Beirut Square in eastern part of the capital, damaging a police vehicle and wounded two policemen aboard, the police said.
The attack also damaged several nearby civilian cars, wounding three people, they said.
Violence persists in Baghdad despite the presence of tens of thousands of U.S. and Iraqi soldiers across the capital in a major security crackdown aimed at curbing insurgency and sectarian violence in the war-torn country.
