An Egyptian court on Saturday sentenced 75 people, including prominent Muslim Brotherhood leaders to death and jailed more than 600 others over a 2013 sit-in which ended with the killing of hundreds of protesters by security forces.

The sentencing concluded the mass trial of some 700 people accused of offences including murder and inciting violence during the pro-Muslim Brotherhood protest at Rabaa Adawiya Square in Cairo.

The government says many protesters were armed and that eight members of the security forces were killed. It initially said more than 40 policemen had died.

Rights groups say over 800 protesters died in the single most deadly incident during the unrest that followed Egypt’s 2011 popular uprising. Amnesty International condemned Saturday’s decision, calling the trial “disgraceful”.

In Saturday’s hearing at the vast Tora prison complex south of Cairo, the court sentenced to death by hanging, several prominent Islamists including senior Brotherhood leaders, Essam al-Erian and Mohamed Beltagi as well as preacher, Safwat Higazi.

According to judicial sources in the country, the Muslim Brotherhood spiritual leader, Mohamed Badie and dozens more were given life sentences while others received jail sentences ranging from five to 15 years.
