A car bomb on a shopping street in Syria's government-controlled third city of Homs killed seven people and wounded 30 on Wednesday, the provincial governor told AFP.

It was the latest in a string of deadly attacks targeting the Akrameh neighborhood of the central city.

"This is a cowardly terrorist act," Governor Talal Barazi said.

The neighborhood is majority Alawite, the sect to which President Bashar Assad belongs, and has been hit by multiple attacks, as well as mortar fire.

In October, a twin car bomb attack outside a school in the district killed 54 people, including 47 children, sparking outrage in the city.

More than 200,000 people have been killed since the conflict in Syria erupted in March 2011.
