Hundreds of Egyptian soldiers formed a cordon around Tahrir Square on Tuesday after eyewitnesses said protesters were forcefully removed by the military, dpa reported.
Witnesses said several protesters were beaten and arrested by the army in order to clear the square of protests, most of which had been directed against the country's military rulers.
In a statement on its Facebook page, the Supreme Council of the Armed Forces thanked youth for their efforts to reopen the square for traffic and for allowing life to resume to normal.
According to witnesses, the military removed three army vehicles from the square that had been set on fire days earlier, while army tanks moved into the square and opened it to traffic.
Days earlier the army tried to remove protesters from the square, leaving three people dead, according to activists, who said soldiers opened fire on protesters.
The military said one person was killed in the clashes that had taken place overnight Friday after hundreds of thousands of people gathered to press the army to move quicker in bringing to trial former president Hosny Mubarak and his associates.
The clearing of Tahrir Square comes as security sources told dpa that Mubarak was hospitalized in Sharm el-Sheikh on Tuesday after suffering medical complications during questioning in the city of el-Tor in South Sinai.
He has been under house arrest there with is wife and two sons pending a corruption investigation.
