Summary The last time such numbers were seen on the square was during the revolution in 2011.
CAIRO (Web News) Huge protests across Egypt calling for the resignation of President Mohammed Morsi have taken place through the night, with some outbreaks of violence.
In the capital, Cairo, tens of thousands of people massed in Tahrir Square and outside the presidential palace in the biggest demonstration there since the 2011 revolution.
At least one person was killed in clashes at Cairo s headquarters of Mr Morsi s Muslim Brotherhood movement.
Four others died in clashes elsewhere.
Millions of protesters across the country accuse the country s first Islamist president of failing to tackle economic and security problems since taking power a year ago.
The demonstration was largely peaceful, but some protesters later threw stones and petrol bombs at the Cairo headquarters of the Muslim Brotherhood.
At least one person was killed when shooting broke out near the political office, activists and a hospital official said.
Meanwhile, thousands of Mr Morsi supporters staged a rally in the Cairo suburb of Nasr City.
A presidential spokesman later urged the protesters to respect the democratic process, referring to Mr Morsi s victory in last year s elections which were widely seen as free and fair.
One clear achievement of President Morsi s opponents has been to get so many people out on to the streets.
The last time such numbers were seen on the square was during the revolution in 2011 which saw the removal of President Hosni Mubarak from power.
The question they face now is how to fashion a political strategy that can rival the organisation of the Muslim Brotherhood, he says.
Another big question, he adds, is what the army will do. The defence minister has warned that the military may intervene if Egypt becomes ungovernable.
