The Cassation Court upheld on Thursday the death and life sentences issued against 57 Muslim Brotherhood defendants over throwing children off a roof in July following the ouster of president Mohamed Morsi.
The court turned down the defendants' challenge against the rulings of the Alexandria Criminal Court that found them guilty of killing four teenagers and attempting to kill eight others.
The convicts were arrested in July after a video showing them throwing children from the rooftop of a building in Alexandria's district of Sidi Gaber went viral.
The footage showed one of the defendants identified as Mahmoud Hassan Ramadan, with a long beard holding a black flag associated with Al Qaeda, stabbing a child and throwing him off the rooftop of the building.
