The former Egyptian president Hosni Mubarak has been moved to a military hospital in Cairo after his health reportedly deteriorated.

Officials and military sources gave various accounts of the 84-year-old's condition, including that he was in a coma and on life support.

However, they said he was not "clinically dead" despite reports to the contrary.

Earlier this month, Mubarak was sentenced to life imprisonment for his role in the killings of demonstrators who helped overthrow him during last year's Arab Spring revolution.

He has reportedly been suffering from poor health for some time now and was wheeled into court on a stretcher during his trial.

The news of his illness comes amid high tension in Egypt, where elections have been taking place to vote in a new, civilian president.

Mubarak's long-time Islamist adversaries in the Muslim Brotherhood say their candidate won a weekend run-off against a former general, but the official result is still unknown.
