The Syrian Observatory for Human Rights (SOHR) says about 90 people - most of them civilians - died when helicopters dropped barrel bombs on Saturday. Aleppo has been the focus of bitter fighting between President Bashar al-Assad's forces and rebels. Meanwhile militants linked to al-Qaeda are reported to have killed the leader of a rival Islamist militia there. Fighters from the Islamic State of the Iraq and the Levant (ISIS) killed Adnan Bakkour during a raid on the base of rivals, the Tawheed Brigades, according to SOHR, a UK-based group that monitors the conflict.
