ROUGH CUT (NO REPORTER NARRATION)
STORY: Opponents of President Mohamed Mursi marched to the presidential palace in Cairo on Friday, while thousands protested at Tahrir Square.
The demonstrators are demanding Mursi's overthrow after the deadliest violence of his seven months in power.
Protests marking the second anniversary of the uprising that toppled Hosni Mubarak have killed nearly 60 people since January 25, prompting the head of the army to warn this week that the state was on the verge of collapse.
Mursi's supporters have clashed with protesters at the palace in the past, although his Muslim Brotherhood has kept its men off the streets in recent days.
The protesters accuse Mursi of betraying the spirit of the revolution by concentrating too much power in his own hands and those of Muslim Brotherhood. The Brotherhood accuses the opposition of trying to overthrow the first democratically elected leader in Egypt's 7,000-year history.
