Anti-Mubarak protesters dominate Cairo Protesters have taken over the centre of the Egyptian capital Cairo on the sixth day of demonstrations against

Protesters have taken over the centre of the Egyptian capital Cairo on the sixth day of demonstrations against the rule of President Hosni Mubarak.

The police, who have been involved in violent clashes with protesters in recent days, have largely disappeared from the streets.

There is a heavy military presence in the city, but soldiers are not intervening.
Meanwhile, al-Jazeera's broadcasts via an Egyptian satellite have been halted, the BBC reports.

The Egyptian government had earlier ordered the Arabic TV channel, which has been showing blanket coverage of the protests, to shut down its operations in the country.
Clashes between protesters and the security forces - mostly riot police - are reported to have left at least 100 people dead across Egypt since rallies began on Tuesday.

Thousands have been injured as violence has flared in cities including Cairo, Suez and Alexandria.

In Cairo, many protesters defied an overnight curfew to camp out in Tahrir (Liberation) Square, the focal point of the demonstrations in the city.

Chants of "Mubarak, Mubarak, the plane awaits" could be heard on Sunday morning, a reference to protesters' hopes that President Mubarak will step down and leave Egypt.
Many protesters once again climbed onto tanks and armoured vehicles around the square, with many soldiers apparently on friendly terms with the anti-Mubarak demonstrators.

Sunday is the start of the working week in the Middle East, but many businesses in the capital are closed. Internet access remains intermittent.

The BBC's Jeremy Bowen says that although key government buildings are under heavy guard, there appears to be a vacuum of authority in large areas of the city.
Throughout the city, armed citizens' groups have formed to respond to the widespread looting and disorder that has accompanied the growing sense of lawlessness.
Across Egypt, thousands of prisoners are reported to have escaped from jails after overpowering their guards.
