The National Coalition for Supporting Legitimacy called for rallying in the streets on Friday to mark 100 days after what it called the coup.

In a statement it issued on Thursday, the coalition said that the gathering point for demonstrators will be Roxi Square in Cairo's Masr al-Gedida, Maadi Corniche, and Mahatta Square in Giza.

"More than 100 days passed since the bloody military coup. During those days, we have had a bitter harvest," the statement said.

The coup resulted in oppressing rival protests, suppressing freedoms, and violating human rights, threatening Egypt's national security. It also caused the political status quo in Egypt to reach a dead end and led to marred constitutional amendments.

Former President Mohamed Mursi was ousted on July 3 following mass demonstrations that called for his removal from power.

Army chief Abdel Fattah al-Sisi announced a roadmap that involves amending the 2012 constitution, appointing the head of the Supreme Constitutional Court as interim president, and holding parliamentary elections to be followed by presidential elections.
