CAIRO — Egypt’s state media say Hosni Mubarak has suffered a “health crisis” while on his way to a Cairo prison hospital after being convicted and sentenced today to life in prison for failing to stop the killing of protesters during last year’s uprising.

State television and the official news agency report that Mubarak, 84, suffered the crisis while aboard the helicopter that ferried him to Torah prison hospital from the court hearing where he was convicted of complicity in the killing of some 900 protesters during the uprising that drove him from power.

Nile News, a state-owned news channel, said Mubarak suffered a heart attack. But that could not be immediately confirmed.
