Former Egyptian president Hosny Mubarak was in a critical condition, but had not died, his lawyer told the state-run newspaper Al Ahram in remarks published Wednesday, dpa reported.
"His health has deteriorated due to lack of medical care at the prison hospital," lawyer Farid al-Deeb said late Tuesday.
Mubarak, who has been serving a life sentence in a prison hospital near Cairo, was transferred late Tuesday to a military medical facility after suffering a stroke, according to security officials.
The state-run Middle East News Agency, citing medical sources, reported that Mubarak, 84, had been declared clinically dead shortly after arriving at the military hospital in the Cairo suburb of Maadi.
Doctors used a defibrillator to restart Mubarak's heart after it stopped for a few seconds, according to state media.
Mubarak's health has been deteriorating since his arrival in the Tora prison hospital, south of Cairo, after a court sentenced him to life in prison earlier this month on charges of complicity in the deaths of protesters.
Mubarak ruled Egypt for three decades before being deposed in February 2011 following a popular uprising.
