Scores of protesters on Friday gathered at Cairo's Abbasiya in preparation for a march to the presidential palace to protest against the rule of the Muslim Brotherhood and President Mohamed Mursi.
Security forces at the palace were absent except at the back side of the palace where 15 central security vehicles and several armoured vehicles are deployed.
Several parties and political powers had called for mass protests this Friday to demand toppling the regime and complete the revolution's objectives.
Participants in today's demonstrations are calling for trying President Mursi and Minister of Interior Mohamed Ibrahim politically and criminally in light of the recent acts of violence.
Their demands also include sacking Premier Hisham Kandil's cabinet, forming a national salvation government, sacking the chief prosecutor general, and forming a committee to draft controversial articles in the constitution as well as bringing justice for the martyrs.
