Car bombs near a maternity hospital and a service station in Baghdad killed at least 28 people Wednesday, the latest in a spate of blasts to hit the city, police and medics said.

One blast struck across the street from the hospital in the frequently targeted Shiite neighborhood of Sadr City, killing at least 10, a police colonel said. Another 29 were wounded.

Residents said a man parked an explosives-laden car in front of a pharmacy. After going inside, he came out saying he had not found what he needed and was going to walk up the street to another pharmacy.

The second explosion occurred near a petrol station in Karrada, a central district of Baghdad that has also been repeatedly targeted.

The explosion ripped through a busy street only a few blocks away from the national theater, killing at least 18 people and wounding 37, the police source said.

An interior ministry official and a hospital source confirmed the casualty figures.

Bomb attacks, including suicide car bombs, have intensified in Baghdad in recent days.
