More than 50 people have been killed by two explosions at a university campus in the northern Syrian city of Aleppo, according to activists and officials.
The blasts reportedly struck an area between Aleppo University's halls of residence and the architecture faculty.
The Syrian Observatory for Human Rights put the death toll at 52, but Aleppo's governor said 82 people were killed.
The BBC's James Reynolds said that Syrian authorities had blamed "terrorists" for the bloodshed, but that it was unclear who was behind the explosions.
