Egypt's state-run news agency reports that doctors have declared former president Hosni Mubarak clinically dead after suffering a stroke in a prison hospital.
Update at 5:43 p.m. ET: Despite the reports that resuscitation efforts had failed, Mubarak's lawyer Farid El-Deeb told Al-Hayat television channel that he is still alive and that efforts to revive him are beginning to have some effect, Ahram Online reports.
The news outlet adds that "it is understood" that Mubarak has been suffering from cancer and heart problems.
Mubarak was sentenced to life in prison June 2 for the killing of pro-democracy demonstrators last year during the "Arab Spring" uprising.
