Footage from the scene of the two explosions at the University of Aleppo shows a six-storey building with all of its windows and parts of its facade missing. Fires can be seen in some of the rooms.
The twisted remains of at least 15 vehicles can be seen and debris covers the ground.
While Assad's opposition blame his troops for the deadly university bombing, the government says extremist group al Nusra is responsible.
Establishing the facts - who bombed what and how many people died - is almost impossible in a country where everyone mistrusts journalists.
