The Syrian television says an unknown number of people may have been killed in a bomb attack in the Syrian capital.

Sunday’s bomb explosion hit the northern Damascus district of Rukn al - Din, said the Syrian state television.

There are reports of victims, added the broadcaster.

Rukn al - Din adjoins the flashpoint district Barzeh, scene of fierce fighting between Syrian forces and foreign - backed militants after the army recently ramped up its efforts to crush the insurgency around Damascus.
