I like to watch sports not the news, but I find our young people very courageous and very kind. They have been perfectly organised and not hurting anyone, not annoying anyone, they are wonderful people. I am very proud of my Egyptian young people."

Tens of thousands of people converged in the heart of Cairo on Tuesday, responding to a call for a million Egyptians to unite in the largest protest in a week of unceasing demands for President Hosni Mubarak to leave after nearly 30 years in power.

A stream of protesters arrived in Tahrir, or Liberation, Square at checkpoints guarded by protesters and the army, which promised on Monday night that it would not fire on protesters.

The announcement was a sign that army support for Mubarak may be unravelling as momentum builds for an extraordinary eruption of discontent and demands for democracy in the United States' most important Arab ally.

The loosely organised and disparate movement to drive Mubarak out is fuelled by deep frustration with an autocratic regime blamed for ignoring the needs of the poor and allowing corruption and official abuse to run rampant.

After years of tight state control, protesters emboldened by the overthrow of Tunisia's president last month took to the streets on January 25 and mounted a relentless and once unimaginable series of protests across this nation of 80 (m) million people, the region's most populous country and the centre of Arabic-language film-making, music and literature.

Egypt's most famous actor Omar Sharif said he was astounded by the protests and added that he was "proud" of the young Egyptians.

"I did not expect ever that somebody was going to come and say to our president to leave or to not be there. So it was a bit of a shock at the beginning at then now I think it's a good thing," he said.

Soviet-era and newer US-made Abrams tanks stood at the roads leading into Tahrir Square.

For days, army tanks and troops have surrounded the square, keeping the protests confined but doing nothing to stop people from joining.

The guns of many of the tanks pointed out from the square.

Military spokesman Ismail Etman said the military "has not and will not use force against the public" and underlined that "the freedom of peaceful expression is guaranteed for everyone."

He added the caveats that protesters should not commit "any act that destabilises security of the country" or damage property.

The protests appeared to be better organised on Tuesday.

Volunteers wearing tags reading "Security of the People", searched those who entered the square.

They said they were watching for government infiltrators or fugitive prisoners who might try to instigate violence.

Authorities shut down all roads and public transportation to Cairo, security officials said.

The protesters, and the Obama administration, roundly rejected Mubarak's announcement of a new government on Monday that dropped his highly unpopular interior minister, who heads police forces and has been widely denounced by the protesters.

Stuffed dummies representing Mubarak were hung from traffic lights at Tahrir Square.

On their chests was written: "We want to put the murderous president on trial."
