Hundreds of protesters marched to Egypt's presidential palace on the second anniversary of the fall of Hosni Mubarak, causing clashes with security forces.
Police fired tear gas and water cannons on the stone throwing protesters marching against current president Mohamed Morsi.
Opposition groups state that President Morsi has betrayed the revolution and shouted slogans calling for his ousting as well as spraying graffiti on the palace walls.
One protestor, Ahmed Farghaly, said,
"We may be few in numbers but we will not back down from fighting criminals dressed up in police uniform".
