Syria crisis: Damascus hit by double 'suicide bombing'

Two suicide bombers have blown themselves up in the centre of the Syrian capital, Damascus, killing 14 people, Syrian state media says.

At least 30 other people were injured in the blasts, in Marjeh Square.

The explosions happened at a police building in the busy commercial district.

The attack comes as regime forces prepare an assault to recapture the northern city of Aleppo after having retaken Qusair from the rebels.
