An Egyptian criminal court sentenced two supporters of ousted President Mohamed Morsi to death on Saturday over killing youths in protests last year, official news agency MENA reported, Xinhua reported.
The two Islamists were accused of throwing young men from the roof of a building in the coastal city of Alexandria during violent acts that erupted over Morsi's disposal.
The court has referred the verdict to the grand mufti, the government's official interpreter of Islamic law, for review. The mufti's opinion is consultative.
The Islamists were also accused of joining terrorist groups, hindering the traffic, burning public utilities, possessing weapons, and disturbing public order.
The trial of another 61 involved in the same case was adjourned to May 19.
On Monday a criminal court in Upper Egypt sentenced some 529 people to death over charges of assaulting police stations last year. Prior to the sentence the authorities had dispersed Morsi supporters' sit-ins in Cairo, leaving more than 1,000 people killed and thousands arrested.
The mass death sentence, which is the biggest in Egypt's modern history, has drawn condemnation from human rights groups, the United Nations and the west.
