Rival political groups in Egypt are to mark the third anniversary of the 2011 uprising which ended in the overthrow of President Hosni Mubarak.

Both supporters of the military-backed government and the Muslim Brotherhood are set to take to the streets.

The anniversary comes as tensions were heightened by a series of bombs in Cairo and clashes across the country which left at least 18 people dead.
