Cairo: A deadly shooting at the site of a sit-in by Muslim Brotherhood supporters in Cairo, demanding the reinstatement of ousted President Mohamed Morsi, has left many people dead, Al-Jazeera reported.
A Brotherhood spokesman said 35 of its supporters were killed in the shootings, a toll later confirmed by the Egyptian health ministry.
Mohamed Mohamed Ibrahim El-Beltagy, a Brotherhood MP, described the incident during the early hours of Monday as a "massacre" during dawn prayers, after police had stormed the site.
About 500 people were also reportedly injured.
A doctor told Al Jazeera that "the majority of injured had gunshot wounds to the head".
The Brotherhood said the dead and the injured have been taken to a makeshift hospital in Nasr City, a neighbourhood in the Egyptian capital.
Speaking to Al Jazeera, Gehad Haddad, a spokesman for Muslim Brotherhood, said that at around 3.30 in the morning, army and police forces started firing at sit-in protesters in front of the Republican Guard headquarters in Cairo.
“We have people hit in the head, we have bullets that exploded as they entered the body, cluttering organs and body parts” he said.
“Every police force in the world understands how to disperse a sit-in. This is just a criminal activity targeting protesters.” But the military said a "terrorist group" had tried to storm the Republican Guard facility, where Morsi is reportedly being held. It also said that an officer had been killed.
