According to BBC News, at least 15 people have been killed and dozens wounded in a series of air strikes on rebel-held area in the Syrian city of Aleppo.

A make shift hospital was hit devastatingly in the eastern shaar district, reports BBC.

It was not clear who was responsible as no one or group has taken responsibility but government forces are seeking to regain control of the city in turmoil.

BBC went further to report that in a defiant speech on tuesday, syrian president Bashir al-Assad promised to retake every inch of the country from his opponents.

Aleppo, he said would be the graveyard where the hopes and dreams of Turkey’s President Recep Tayyip Erdogan – a key backer of the rebels – would be buried.
