A car bomb exploded on the edge of the central Syrian city of Hama Sunday morning, killing at least 30 people, Syria’s state TV said.

The state news agency SANA said Syrian rebels drove the truck laden with over a ton of explosives into the post at the eastern entrance of the city on Sunday.

SANA said the explosion appeared to have set ablaze a gasoline truck nearby, increasing the damage and casualties.

The British-based Syrian Observatory for Human Rights said the al-Qaida-linked Jabhat al-Nusra, or al-Nusra Front, had carried out the attack.

Car bombs are most frequently used by hard-line al-Qaeda-linked militants fighting among the rebels.
