Egyptians Mark Second Anniversary of Violent Protests
Dozens were killed in 2011 clashes
Opponents and supporters of Egypt's military-backed government have taken to the streets to mark the second anniversary of bloody protests.
Crowds gathered in Cairo's Mohammed Mahmoud Street to commemorate those killed, according to state-run media.
Meanwhile protesters vandalised a memorial only hours after it was unveiled in Tahrir Square.
Dozens of people died in fierce clashes between demonstrators and security forces in November 2011.
The violence took place as protesters rallied against the Supreme Council of the Armed Forces (Scaf), the military leadership that took power after the fall of President Hosni Mubarak earlier that year.
