Syrian government forces have killed dozens of civilians in air raids in the northern city of Aleppo, activists say.

The Syrian Observatory for Human Rights (SOHR) says about 90 people - most of them civilians - died when helicopters dropped barrel bombs on Saturday.

Unverified amateur footage appears to show the aftermath of attacks on the city, which has seen bitter fighting between President Bashar al-Assad's forces and rebels.
