Egypt is bracing for rival mass demonstrations, amid tight security in the increasingly polarised nation, BBC News said.
President Mohammed Morsi's supporters are to hold "open-ended' rallies – two days ahead of the opposition protests calling for the president to resign.
Meanwhile, one person died and a number of others were injured in clashes in northern Egypt late on Thursday, June 27.
Morsi in a speech marking his first year in office earlier said the unrest was "threatening to paralyse" Egypt. Troops have been deployed in the capital Cairo and other cities.
Morsi, who hails from the Muslim Brotherhood, became Egypt's first Islamist president on 30 June 2012, after winning an election considered free and fair. His first year in office has been marred by constant political unrest and a sinking economy.
