One person died in fresh clashes on Saturday, as the rift between Egypt's military rulers and activists who ousted Hosni Mubarak deepened just days before landmark polls. The namng of a new prime minister, Kamal al-Ganzuri who once served as premier under Mubarak, failed to satisfy demands for change ahead of parliamentary elections due to start on Monday. A 19-year-old demonstrator was fatally injured when police attacked a protest in front of the cabinet headquarters that rejected Ganzuri's appointment. The victim died of massive internal bleeding from multiple fractures to the pelvis, possibly caused by a heavy vehicle, a medic told AFP. Witnesses said that a police van had charged into the demonstrators. Thousands spent another night in Tahrir Square -- the symbolic heart of protests that toppled Mubarak -- where they vowed to stay until their demand of civilian rule is met. Dozens of tents have been pitched, a rubbish collection station was set up and street vendors roamed the square in a sign that protesters were settling in for the long haul. In a television address, Ganzuri said he would formalize his government "before the end of next week" and would allocate some portfolios to younger people. But protesters in the square quickly rejected his appointment, saying he was not the man to lead a transition to democracy. "We do not want someone who has been selected by the military council, we want a civilian who was with us in Tahrir during the revolution, someone who has the confidence of the people," said one protester, Omar Abdel Mansur. On Friday hundreds of demonstrators in the square branched off to the nearby cabinet offices to block Ganzuri from entering the building, chanting "revolution" and "Ganzuri is a former regime leftover." The Tahrir protest was countered by a rival demonstration in a square about three kilometers away, where more than 10,000 people gathered Friday night to show support for the military.
