Thousands of anti-Morsi protestors started gathering Saturday in Tahrir Square amid tight security procedures imposed by the square's popular committees.
The popular committees have closed some entrances to the square to prevent cars from entering. The committees have also set up inspection points at some of the open entrances to Tahrir Square aimed at preventing arms entering that could be used in attacks on protestors.
The National Salvation Front (NSF) and Rebel campaign have called for protests in Tahrir Square to protect the "achievements of 30 June" — referring to mass protests last Sunday that led Wednesday to the ouster of Mohamed Morsi as president.
Millions took to the streets across Egypt 30 June calling for Morsi to step down and for early presidential elections to take place, one year into Morsi's four-year term as president.
Four days after the 30 June protests that spread nationwide, Defence Minister Abdel Fattah El-Sisi announced an army "roadmap" to take Egypt forward. The roadmap included dismissing Morsi, suspending the constitution (drafted and passed during Morsi's rule), and appointing an interim president until a date is set for presidential elections.
Adly Mansour, head of the High Constitutional Court, was sworn in as interim president Thursday.
Hundreds of thousands of pro-Morsi supporters held rallies across Egypt on Friday to protest what they label a "coup d'état" against the country's first democratically-elected head of state, vowing to continue protesting until he is reinstated.
Clashes erupted Friday between supporters of Morsi and opponents and security forces. The clashes, seen across 19 governorates, left 36 dead and 1138 injured, according to Egypt's health ministry.
