A state of calm prevailed on Friday morning in Cairo's Tahrir Square before a planned million-man demonstration which several revolutionary parties and forces have called for.
According to those parties and forces, participants in today's demonstration demand holding early presidential elections, releasing all detainees, drafting a new constitution, and avenging the martyrs.
Some political powers will garner support for the rebellion movement "Tamarod" whose aim is to collect support for a no confidence vote against President Mohamed Mursi's government.
The demonstration includes three marches from mosques all headed towards Tahrir Square.
The Dostour Party, the Free Egyptians Party, the Popular Socialist Alliance Party, Tamarod movement, the Black Bloc, April 6 movement and Kefaya movement are among the most prominent parties and movements taking part in the demonstration.
The Interior Ministry has provided reinforcements around its headquarters in downtown Cairo before the planned demonstration.
Around 21 state security vehicles, 3 armoured vehicles and a fire engine were deployed around the ministry's gates, the Middle East News Agency reported.
