Egypt’s Muslim Brotherhood and its Islamist allies called for more protests on Tuesday, after at least 51 people were killed in Cairo on Monday when the army opened fire on supporters of ousted Islamist President Mohamed Morsi.

Meanwhile, Egypt’s interim leader Adly Mansour has outlined his timetable for new elections. His decree says a panel to amend the constitution must be formed within 15 days and general elections could then be held by February.

Morsi supporters blame the military for opening fire on them outside the Republican Guard compound where the former president is believed to be held. He was ousted by the military on Wednesday. The army said it opened fire in response to an attack on its soldiers.

“In protest against the military coup that was followed by suppressive actions, topped by the Republican Guard massacre that took place at dawn, we call on all citizens and honorable people to protest on Tuesday across Egypt,” Hatem Azam, a spokesman for a coalition led by the Muslim Brotherhood, told a news conference.

Demonstrators directed most of their anger at Commander-in-Chief of the Armed Forces General Abdel Fattah al-Sisi. “There is no god but Allah, and al-Sisi is an enemy of Allah,” chanted demonstrators in the square.
