Ten people were wounded in separate bomb attacks and mortar barrage in Baghdad on Saturday morning, an Interior Ministry source said.
Seven people were wounded, including four policemen, in two bomb explosions outside a liquor store in Baghdad southern district of al-Amil, the source told Xinhua on condition of anonymity, Xinhua reported.
In a separately incident, four Katyusha rockets landed in central Baghdad early in the morning, three of them struck Baghdad heavily fortified Green Zone, the source said without giving further details about the bombings.
The fourth rocket hit Abu Nawas Street across the Tigris River, wounding two people, the source said.
The Green Zone, which houses some of the Iraqi government offices and U.S. embassy, have been frequently targeted by insurgents' mortar and rocket attacks. The roughly 10 square km zone is located on the west bank of the Tigris River which bisects the Iraqi capital.
Also in the capital, a civilian was wounded when a sticky bomb attached to his car detonated near an intersection in Baghdad's central district of Karrada, the source added.
Violence and sporadic high-profile attacks are still common in Iraqi cities as part of recent deterioration in security which shaped a setback to the efforts of the Iraqi government to restore normalcy in the country after violence-torn Iraq held parliamentary elections eight months ago.
