Egypt has sentenced 75 people to death, over a 2013 pro-Muslim Brotherhood sit-in which ended with the killing of hundreds of protesters, judicial sources said on Saturday.
Others being tried in the case, including Brotherhood spiritual leader Mohamed Badie, were handed life sentences.
Those sentenced to death by hanging include senior Brotherhood leaders Essam al-Erian and Mohamed Beltagi and prominent preacher Safwat Higazi, the sources said. They are accused of security-related offences including incitement to violence, murder and organising illegal protests.
Rights groups have criticised the mass trial of more than 700 people in what has become known as the Rabaa case, after Rabaa Adawiya square where the sit-in took place in Cairo.
The dispersal of the sit-in in August 2013 came weeks after President Abdel Fattah al-Sisi, then military chief, ousted president Mohamed Mursi after protests against Brotherhood rule.
Amnesty International says more than 800 protesters were killed. The government has said many protesters were armed, and that 43 police were killed.
