Two suicide bombers detonated their explosives, killing at least two security officers in the Syrian coastal city of Tartous, Syrian state television reported after midnight on Sunday.

It said the officers were part of a security patrol that stopped the bombers, who then blew themselves up. Others were injured in the blasts, including civilians, state TV said. It gave no further details.

British-based monitoring group the Syrian Observatory for Human Rights said there had been explosions from suicide bombers in Tartous and that at least two people were killed.

Tartous has not been targeted for several months, and has largely escaped the violence that has engulfed other areas of the country.
