Syrian activists say a car bomb north of the capital has killed at least 13 people, including 10 policemen.

The Britain-based Observatory for Human Rights said Monday the blast struck overnight near the police headquarters in the town of Deir Atiyeh. The Observatory said a child was among the three civilians killed.

Syria's state news agency confirmed the attack. It said a suicide bomber detonated an explosives-laden car in a residential area of the town, causing an unknown number of casualties.

The agency said "terrorists" were behind the attack — a government term for rebels fighting to topple President Bashar Assad's regime.
