After earlier conflicting reports that Egypt's ex-president Hosni Mubarak was on life support, senior officers and military sources now say that Mubarak is not clinically dead, as was briefly reported by the state news agency, according to sources.

Earlier Tuesday, Egypt's state-run news agency reported that doctors had declared Mubarak clinically dead after he suffered from a stroke in the hospital.

However, the Egyptian officials are saying that the ousted Egyptian president was moved from prison to a military hospital on Tuesday after a health crisis, Reuters reported.

There has been no clear statement from independent medical experts on what ails him, Reuters said, though state media have reported a variety of illnesses from shortage of breath to heart attacks.

Mubarak's lawyer Farid El-Deeb claims Egypt's ex-president is still alive, Ahram Online reports.

He is completely unconscious. He is using artificial respiration, one military source told Reuters. Another source that spoke to Reuters dismissed that report and said it was too early to say he is officially dead.

Earlier this month, the 84-year-old president was sentenced to life in prison for his failure to stop the killings of protesters during the 2011 Egyptian Arab Spring uprising.

Meanwhile, thousands of Egyptians flooded central Cairo to protest a declaration by Egypt's ruling generals extending their grip on power.

The protests were called by Egypt's Muslim Brotherhood, which has vowed to challenge the military's recent moves regarding foreign policy and the country's constitutional drafting process, Voice of America reported.
