Attackers armed with knives and machetes have clashed with pro-democracy demonstrators in Cairo.
The incident took place on Wednesday in Tahrir Square, the epicenter of the anti-government protests that led to the resignation of President Hosni Mubarak. Television video from the square shows the two sides throwing rocks at each other. News reports say at least two people were injured.
The unrest erupted after hundreds of pro-democracy activists had gathered for a rally in the square. The French News Agency (AFP) says one activist described the attackers as "pro-Mubarak thugs."

Witnesses say Christians and Muslims threw rocks at each other before riot police fired warning shots in an effort to break up the activists.
