Clashes rage in Tahrir Square

Clashes have broken out between pro- and anti-government demonstrators in the Egyptian capital Cairo.

Protesters from both sides threw stones at each other in Tahrir Square, the epicentre of ongoing opposition demonstrations against President Hosni Mubarak for the past nine days

The health ministry said at least one person had been killed and another 400 injured in Wednesday's violence.

Al Jazeera correspondents, reporting from the scene, said clashes were still raging and that petrol bombs were being hurled.

"Someone - a few people actually - are dropping homemade bombs into the square from the buildings surrounding it. Gunshots occasionally ringing out across downtown," our online producer said.

Earlier, witnesses said the military allowed thousands of pro-Mubarak supporters, armed with sticks and knives, to enter the square. Opposition groups said Mubarak had sent in thugs to suppress anti-government protests.

One of our correspondents said the army seemed to be standing by and facilitating the clashes. Latest reports suggest that the centre of the square is still in control of the protesters, despite the pro-Mubarak supporters gaining ground.

'Absolute mayhem'

Witnesses also said that pro-Mubarak supporters were dragging away protesters they had managed to grab and handing them over to security forces.

Salma Eltarzi, an anti-government protester, told Al Jazeera there were hundreds of wounded people.

"There are no ambulances in sight, and all we are using is Dettol," she said. "We are all so scared."

Aisha Hussein, a nurse, said dozens of people were being treated at a makeshift clinic in a mosque near the square.She described a scene of "absolute mayhem", as protesters first began to flood into the clinic.
People are coming in with multiple wounds. All kinds of contusions. We had one guy who needed stitches in two places on his face. Some have broken bones."

Meanwhile, another Al Jazeera correspondent said men on horseback and camels had ploughed into the crowds, as army personnel stood by.

At least six riders were dragged from their beasts, beaten with sticks by the protesters and taken away with blood streaming down their faces.

One of them was dragged away unconscious, with large blood stains on the ground at the site of the clash.

The worst of the fighting was just outside the world famous Egyptian Museum, which was targeted by looters last week.

Al Jazeera's correspondent added that several a group of pro-government protesters took over army vehicles. They also took control of a nearby building and used the rooftop to throw concrete blocks, stones, and other objects.

Soldiers surrounding the square took cover from flying stones, and the windows of at least one army truck were broken. Some troops stood on tanks and appealed for calm but did not otherwise intervene.

Many of the pro-Mubarak supporters raised slogans like "Thirty Years of Stability, Nine Days of Anarchy".
