CAIRO (AP) — Egypt’s Hosni Mubarak was being kept alive by life support after he was rushed from prison to a military hospital in a rapidly worsening condition, officials said. The 84-year-old ousted leader’s health crisis added a new element of uncertainty just as a potentially explosive fight opened over who will succeed him.The state news agency MENA said Mubarak was “clinically dead” when he arrived at the hospital and that doctors used a defibrillator on him several times. It initially said the efforts were not successful.But the official said Mubarak was put on life support. He had no further details on his condition. The official spoke on condition of anonymity because he was not authorized to talk to the press.The developments add further layers to what is threatening to become a new chapter of unrest and political power struggles in Egypt, 16 months after Mubarak was ousted by a popular uprising demanding democracy. Egyptians were uncertain about Mubarak’s fate, about who will succeed him and about whether his successor will have any power.The campaign of Mubarak’s former prime minister, Ahmed Shafiq, said Tuesday he has won Egypt’s presidential election, countering the Muslim Brotherhood’s claim of victory for its candidate, Mohammed Morsi.
