Doctors used a defibrillator twice on Hosni Mubarak when they could not find a pulse, security officials said, in the latest crisis for the ousted Egyptian president since he was sentenced to life and moved to a prison hospital nine days ago.

Officials said the 84-year-old Mubarak was slipping in and out of consciousness and was being fed liquids intravenously.

Mubarak also reportedly lost consciousness several times on Sunday and officials have said he is suffering from high blood pressure, depression and breathing difficulties.
