Hundreds of thousands of Egyptians flooded into the streets on the first anniversary of Islamist President Mohamed Mursi's inauguration on Sunday to demand that he resign in the biggest challenge so far to rule by his Muslim Brotherhood.
Waving national flags and chanting "Get out!", a crowd of more than 200,000 massed on Cairo's central Tahrir Square. It was the largest demonstration since the 2011 uprising that overthrew Mursi's predecessor, Hosni Mubarak.
"The people want the fall of the regime!" they shouted, echoing the Arab Spring rallying cry that brought down Mubarak - this time yelling it not against an ageing dictator but against the first elected leader in Egypt's 5,000-year recorded history.
While the main protests were peaceful, at least one Mursi supporter was shot dead and 37 people injured in fighting in the town of Beni Suef, south of Cairo, and dozens suffered gunshot wounds during an attack on a Muslim Brotherhood office in Housh Eissa, in the northern Nile Delta.
