Deadly blasts rip through Aleppo square

At least thirty people have been killed and dozens injured in a series of bomb explosions in the centre of Syria's second city, Aleppo.

Several blasts went off levelling buildings in Saadallah al-Jabri square which is in a government controlled district of the city.

Aleppo has become a key battleground between rebels and forces loyal to President Bashar Assad.

Rebels have not been able to take over the city, but despite massive bombardments by artillery, tanks and aircraft, government forces have failed to dislodge opposition fighters.
