At least six people were killed and some 18 others wounded in car bomb and roadside bomb explosions in central Baghdad on Wednesday, an Interior Ministry source said.
The incident occurred when a booby-trapped car detonated in the morning near a traffic police headquarters near the al-Nahdha parking lot in central Baghdad on the east side of Tigris River, the source said on condition of anonymity.
Minutes later, a roadside bomb went off when security forces and civilians gathered to examine the first blast, the source said.
A total of at least six people were killed and more than 18 others wounded, the source said.
Policemen and civilians were among the killed and wounded people, the source said, adding that the toll could rise as ambulances and civilian cars were transferring victims to several nearby hospitals.
The powerful blast also caused damages to several civilian cars, he added.
Despite the security gains in recent months in Iraq, there are still sporadic bombings, which shape setback to the Iraqi government.
