Fourteen-year-old Qusai Abtini was killed as he tried to escape during the most recent shelling of the city.
An Al Jazeera team in Aleppo was caught in an air strike on Thursday while reporting on fighting inside the war-torn city.
Correspondent Milad Fadhel and cameraman Mohamed Kheir Elhek survived, suffering minor injuries in the blast which they caught on camera.
The team were forced to take shelter inside a building for seven hours while shelling went on around them.
“The bombing in that area is intense,” Fadhel said later.
“One minute we were thinking we were going to die, but luckily we survived by just being injured by the blasts.
“We are talking about more than 60 explosions happening every minute.”
Opposition activists reported that at least 60 people were killed in the Syrian city overnight Thursday through to Friday morning.
Government forces and rebels are fighting for control of the city, which was Syria’s economic hub before the civil war broke out in 2011.
