CAIRO - Egypt's Interior Ministry confirmed on Monday that former president Hosni Mubarak is in a coma.
His two sons who face charges of insider trading and money laundering were reportedly at his side in hospital.
The 84-year-old former statesman was sent to a prison hospital in Cairo, after he was sentenced to life behind bars for the killing of pro-democracy demonstrators in 2011.
Mubarak was already suffering from health problems during sentencing and attended court proceedings on a gurney.
On Monday, Egypt's prison authority approved a request to let Hosni Mubarak's eldest son stay close to him in a prison hospital in response to the former president's deteriorating health.
Mubarak requested his son Alaa be moved close to him after the authorities earlier agreed to a similar request to have his youngest son Gamal brought next to him.
Citing a security source in the Interior Ministry, the report said the latest decision was in response to "a deterioration in his health".
Mubarak was jailed for life on 2 June for failing to prevent the killing of protesters who rose up against him, but the acquittal of senior police officers for lack of evidence angered many Egyptians who believe the ex-president may win an appeal.
Since Mubarak was moved to Tora prison hospital from a plush military hospital where he was held during the 10-month trial, speculation has been rife about his state of health. Such rumours also frequently recurred as he aged in office.
Security sources said last week that Mubarak was given artificial respiration five times in one day and doctors recommended he be moved to a military hospital or back to the medical facility he was in prior to his conviction.
He has also reportedly slipped in and out of a coma at times, although prison sources said on Monday he was awake and with his sons.
Gamal, once seen as being groomed for the presidency, and Alaa are also being held in Tora prison pending a trial over a case of alleged stock market manipulation. Corruption charges they had faced with their father in his trial were quashed.
Mubarak's wife Suzanne and the wives of his two sons also visited the ex-president on Sunday, the state news agency reported, quashing rumours that had briefly swirled suggesting the former president had died.
About 200 supporters of Mubarak protested outside Tora prison on Saturday demanding he be moved to a hospital outside prison.
