CAIRO (AP) — An Egyptian security official says former president Hosni Mubarak has been slipping in and out of consciousness, more than a week after he was transferred to a hospital inside a Cairo prison to serve his life sentence.

The official says Mubarak’s wife, former first lady Suzanne Mubarak, and her two daughters-in-law were visiting him in prison Sunday morning after rumors circulated that he had died. Mubarak was admitted to the Torah prison after a judge convicted him on June 2 of failing to stop the killings of protesters during last year uprising which forced him out of power.

The official says Mubarak lives only on liquids and yogurt. The official, who is in the prison, spoke on condition of anonymity because he is not authorized to speak to the media.
