Official: Egypt's Hosni Mubarak is on life support Updated 6:33 PM ET (CBS/AP) CAIRO - Following reports Hosni Mubarak had suffered a stroke, a security official says the former Egyptian president is on life support. Earlier Tuesday, Mubarak had been moved from prison to a military hospital after his condition rapidly worsened. Cairo-based MENA news agency also reported Mubarak has been declared "clinically dead," which is defined as the moment the heart stops beating and respiration ceases, but the patient is not brain dead yet. MENA also quoted an official as saying doctors used a defibrillator on him several times, but 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. Interior Ministry spokesman Alaa Mahmoud said earlier Tuesday the 84-year-old Mubarak was moved by ambulance from the hospital in Torah Prison to nearby Maadi Hospital in southern Cairo. The state news agency had said Mubarak's health condition was rapidly deteriorated, with his heart stopping briefly, then suffering a stroke.
