SCEPTICISM:
On Tuesday, Mubarak - who ruled Egypt for 30 years - was transferred by helicopter to intensive care at the Maadi armed forces hospital after suffering a stroke, state media said.
Correspondents say the hospital is better equipped to deal with such conditions than the prison hospital where he was being treated.
The former leader is now said tobe unconscious and on life support.
Doctors are said to have used a defibrillator on him several times. The device delivers an electric shock to the heart to try to re-establish a normal heartbeat.
There are lots of police officers currently deployed outside the hospital, the BBC's Kevin Connollyreports.
There are also small groups of people - both Mubarak's supporters and protesters against him - who have gathered outside the building, our correspondent says.
One woman, a supporter, was almost shaking with emotion and saying "I love him".
Another supporter, a man, stoodholding a poster of Mubarak. "He is my father. I love him more than my father. The Muslim Brotherhood are criminals. They have destroyed our country. Mubarak kept us in peace for 30 years," he said.
A group of anti-Mubarak young men responded by shouting:"We are poor, and he did nothing for us. His family ate meat and we were starving."
"I'm ready to hammer his grave with my shoe," another protester added.
Egyptians will be very sceptical about any reports about the former president's health, the BBC's Jon Leyne in Cairo says.
Before Mubarak's trial began, his lawyer said he was in a coma, only for the former president to appear - alive and conscious, if not particularly well - in court, our correspondent says.
Now there will be fears that the state of Mubarak's health could be used as a distraction, as Egypt waits for the result of the hotly disputed presidential election. Source: www.bbc.co.uk
