Alexandria Criminal Court sentenced two men to death Saturday for throwing children off a roof last July, two days after Islamist president Mohamed Morsi's ouster.
They faced charges of manslaughter, thuggery, violence, illegal possession of weapons, and disturbing public order.
The verdicts were delivered amid a heavy security presence outside the court.
The defendants papers have been transferred to the Office of the Grand Mufti, the country's official authority for issuing religious edicts, as Egyptian law stipulates that all death sentences must be reviewed by the grand mufti for ratification.
The convicts were arrested last 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, with a long beard holding a black flag associated with Al-Qaeda, stabbing a child and throwing him off the rooftop of the building.
Also standing trial are another 60 defendants — allegedly Muslim Brotherhood members — accused of violent behaviour and thuggery in Sidi Gaber on 5 July 2013.
Their trial has been postponed to 19 May.
Morsi's ouster was followed by nationwide violence that saw clashes between his supporters, opponents and the police. Violence intensified in mid-August after the deadly dispersal of two main pro-Morsi protest camps, in Rabaa Al-Adawyia and Nahda squares in Cairo and Giza respectively.
