riot police beat protesters and dismantled a small tent city set up to commemorate revolutionary martyrs in Cairo's Tahrir Square on Saturday.
The clashes occurred after activists camped in the central square overnight following a massive Friday rally. The military tolerates daytime demonstrations in the central square, a symbol of the country's Jan. 25-Feb. 11 uprising, but claims that long-term occupation paralyzes the city.
The number of protesters swelled to nearly 600 people as news of the scuffles spread in the city, and thousands more riot police streamed into Tahrir Square blocking off the entrances and clashing with protesters.
Police were seen beating activists who challenged them and an Associated Press cameraman saw police arrest three people who refused to leave.
Stubborn protesters played cat-and-mouse with riot police as they were chased outside of the square and into side streets. "We are using side streets to pretend to run errands, but we are just regrouping and going back," said Sahar Abdel-Mohsen, who joined in the protest on Saturday afternoon, after a call went out on Twitter telling people to come down to Tahrir.
Protesters were chanting anti-security slogans including, "Riot Police are Thugs and Thieves" and "Down with the Marshal" referring to Field Marshal Hussein Tantawi, Egypt's military ruler.
On Friday, tens of thousands of Islamists as well as leftists and other young activists had massed in Tahrir Square, confronting Egypt's ruling military council with the largest crowd in months to protest a document which would give the generals special powers over a future elected government.
Most of this year's rallies in Tahrir Square since Mubarak's ouster have been led by liberal- or left-leaning groups, but Islamists dominated Friday's protest.
While united against giving the army new powers, however, Islamists and liberals were jockeying among themselves for votes in crucial parliamentary elections only 10 days away.
The stakes are higher for all sides than at any time since the uprising ousted President Hosni Mubarak in February. The victors will help choose who will draft a new constitution, thus defining the character of post-revolutionary Egypt.
