Mubarak, who ruled Egypt for three decades until overthrown in 2011, was on life support in hospital, military officials said on June 19, 2012, but they denied a report he was clinically dead. Earlier the state news agency, amid high tension over the election of a new president, quoted medical sources as saying the former head of state, aged 84, was "clinically dead". [Photo/Agencies]
