At least seven people were killed Thursday after a car bomb detonated in the Wadi Dahab district of Homs in Syria.

Five of the seven killed were civilians, the Syrian Observatory for Human Rights told Associated Press. Wadi Dahab is a neighborhood whose residents are largely loyal to Syrian President Bashar Assad. The identities of the other two killed were unclear.

No groups have yet taken responsibility for the car bombing, although the Jordan-based Al Bawaba media outlet noted that the al-Qaida linked al-Nusra Front rebel group has often claimed responsibility for car bombings in Alawite neighborhoods such as Wadi Dahab.

Anti-government rebels withdrew from their strongholds in Homs last month as part of an agreement following a two-year offensive by the military, AP reported. The pact quelled some of the violence in Homs, but car bombs are still used to target pro-government areas of the city.

Syria’s state news agency said 25 people were wounded in the car bomb attack.
