Egypt was on Friday bracing for mass protests by the opposition to mark the second anniversary of the revolt that toppled Hosni Mubarak.
The opposition called for rallies against President Mohammed Morsy and his Muslim Brotherhood group, accusing them of tightening their hold on power.
The Brotherhood and other Islamists, who dominate parliament, are celebrating the anniversary of the revolt which brought them to power.
“I call on everyone to take part and go out to every place in Egypt to show that the revolution must be completed,” opposition leader Mohammed ElBaradei said.
Mr. Morsy, Egypt’s first freely elected president, faces the challenge of trying to revive the economy and ease tensions between Islamists and opposition groups.
On Thursday, Morsy blamed remnants of the Mubarak regime of trying to undermine stability. “I hope all groups will remain peaceful during celebrations,” Mr. Morsy said.
“A structural reform is taking place in the state’s institutions to fulfil the revolution’s demands. I’m also working with the government to solve the problems of slum areas in Egypt.” Some 16 people were injured in clashes on Thursday between police and protesters in Cairo.
