Egyptian army tanks and soldiers moved to end violence between anti-government protesters and supporters of President Hosni Mubarak in Cairo's central square on Thursday after standing by for nearly a day as the two sides battled with rocks, sticks, bottles and firebombs.
Hours after automatic gunfire hit the anti-government protest camp at Tahrir Square, killing at least three protesters, soldiers carrying rifles could be seen lining up between the two sides around 11 a.m.. Several hundred other soldiers were moving toward the front line.
Four tanks cleared a highway overpass from where Mubarak supporters had hurled rocks and firebombs onto the protesters.
The pre-dawn firing escalated what appeared to be a well-orchestrated series of assaults on the demonstrators that began when Mubarak supporters charged into the square on horses and camels on Wednesday afternoon, lashing people with whips, while others rained firebombs and rocks from rooftops.
Anti-Mubarak demonstrators traded showers of rocks and other projectiles in a counter-assault that drove their assailants out of the square within hours. Anti-government protesters took army trucks and set up an ad-hoc frontline on the northern edge of the square, near the famed Egyptian Museum. The two sides traded volleys of rocks and Molotov cocktails for much of the night, until sustained bursts of automatic gunfire and powerful single shots rained into the square starting at around 4 a.m. and continuing for more than two hours.
The protesters accused Mubarak's regime of unleashing a force of paid thugs and plainclothes police to crush their unprecedented nine-day-old movement, a day after the 82-year-old president refused to step down. They showed off police ID badges they said were wrested from their attackers. Some government workers said their employers ordered them into the streets.
The anti-Mubarak movement has vowed to intensify protests to force him out by Friday.
The notion that the state may have coordinated violence against protesters, who had kept a peaceful vigil in Tahrir Square for five days, prompted a sharp rebuke from Washington, which has considered Egypt its most important Arab ally for decades, and sends it $1.5 billion a year in aid.
"If any of the violence is instigated by the government, it should stop immediately," said White House Press Secretary Robert Gibbs.
Protest organizer Mustafa el-Naggar said he saw the bodies of three dead protesters being carried toward an ambulance before dawn Thursday. He said the gunfire came from at least three locations in the distance and that the Egyptian military, which has ringed the square with tank squads for days to try to keep some order, did not intervene.
Footage from AP Television News appeared to show two more dead bodies being dragged along the highway overpass where the Mubarak supporters were massed.
At one point a tank spread a thick smoke screen along the overpass, just to the north of the square, in an apparent attempt to deprive attackers of a high vantage point. Farther back in the square, around 4,000 protesters were holding out. A man with a microphone called out the names of the missing - most of them children - from the hours of clashes.
At an open-air clinic in the middle of the square, doctors treated the injured. Dr. Amr el-Yamani said most had suffered head injuries from hurled rocks.
Mustafa el-Fiqqi, a senior official from the ruling National Democratic Party, told The Associated Press that businessmen connected to the ruling party were responsible for what happened.
Egyptian Health Minister Ahmed Sameh Farid said three people died and at least 611 were injured in Tahrir Square on Wednesday. One of those killed fell from a bridge near the square; Farid said the man was in civilian clothes but may have been a member of the security forces.
Farid did not say how the other two victims, both young men, were killed. It was not clear whether they were government supporters or anti-Mubarak demonstrators.
After years of tight state control, protesters emboldened by the uprising in Tunisia took to the streets of Cairo and other cities on Jan. 25 and mounted a once-unimaginable series of demonstrations across this nation of 80 million.
State TV said Vice President Omar Suleiman called "on the youth to heed the armed forces' call and return home to restore order." From the other side, senior anti-Mubarak figure Mohamed ElBaradei demanded the military "intervene immediately and decisively to stop this massacre."
Secretary of State Hillary Rodham Clinton spoke with Suleiman to condemn the violence and urge Egypt's government to hold those responsible for it accountable, State Department spokesman P.J. Crowley said.
