It's all kicking off between the protesters and the supporters of Mubarak now:
http://www.bbc.co.uk/news/world-middle-east-12345656Clashes have erupted in Cairo between supporters of Egyptian President Hosni Mubarak and [the] demonstrators calling on him to step down immediately.
Thousands of rival protesters have been throwing stones at each other and fighting with fists, whips and sticks in the capital's Tahrir Square.
...
Up to 2,000 anti-Mubarak demonstrators saw out a cold night in Tahrir Square, the main focus of the protests, saying the president's pledge was insufficient and chanting: "We will not leave!" They want to see him deposed and punished.
At the scene Ian Pannell, BBC News, Cairo, said, "We're in the middle of a very fluid situation - this is entirely dangerous, entirely provocative. Thousands of pro-Mubarak forces are now surging into Tahrir Square."
There was a cordon set up by the anti-Mubarak protesters to try and hold them back. The army were in the middle. They didn't take sides.
And basically there were too many of them. So they are now surging forward.
We've just seen one man being attacked - being kicked and punched and hit with a stick. And we've also seen protesters pulling down signs that are against President Mubarak.
There's a lot of anger on the streets at the moment, a lot of argument, fists are flying. And who knows where this will end.
But on Wednesday, thousands of supporters of President Mubarak surged into the square, dismantling barricades.
"You guys have made your point clear, let the man (Mubarak) take care of you until his time is up. Mubarak wants stability and we want stability as well," said Mohamed Shafik.
"Let Egyptians go home and look after their families," the 51-year-old pharmacist told Reuters news agency.
Television footage showed opposing groups facing off chanting slogans, and later fighting. Some government supporters rode horses and camels and wielded whips. Later, gunshots were heard in the square.
BBC Middle East editor Jeremy Bowen, who is in Tahrir Square, said the clashes were becoming increasingly violent and he had seen people with nasty wounds.
The anti-Mubarak protesters have been accusing the army of moving aside to let in their pro-government rivals.
The troops guarding the square have not intervened. The crowds of protesters began to thin after the fighting broke out.
Clashes between the rival groups were also reported in Egypt's second city, Alexandria.
And I'd just like to finish by adding this great little quote from
The Daily Mash:
"Got the entire country setting fire to things and calling for your head? Why not get all your staff to swap desks? That should calm things down a treat."
