Egypt's ruling military council have apologised after military police beat protesters in Cairo's Tahrir Square. A security official and witnesses said that shortly after midnight, military police surrounded protesters, beating them with batons and using teargas to disperse the crowd of several hundred that had gathered to push for reforms. The Supreme Council of the Armed Forces said that what happened late on Friday night was the result of unintentional confrontations between the military police and the youth of the revolution. It stressed that it did not and will not issue orders to attack the youth, and all measures will be taken to ensure this will not happen again. But activists launched a Facebook call for fresh protests on Saturday to denounce the army's use of force.On Friday, thousands of Egyptians rallied in the square – the focal point of anti-government protests that toppled president Hosni Mubarak, to celebrate the success of their revolution and call for a new government purged of old guard remnants. They demanded the replacement of the government of Prime Minister Ahmad Shafiq. Even after a reshuffle on Wednesday, a number of key portfolios, including foreign affairs and defence, are still in the hands of Mubarak regime veterans.
