Update 1:15 a.m.: CNN spoke with Mubarak's lawyer who told them he's currently in a coma. "He has been in a coma for hours now," the lawyer said. "He has had water on the lungs for 10 days now and his blood pressure is down today, which obstructed his breathing and forced doctors to put him on a respirator. He was given medicine intravenously to relieve the brain clot, and electric shocks were used to revive him but there was no substantial response. He is not dead as reported."
Update 9:50 p.m.: Reports of former Egyptian President Hosni Mubarak being "clinically dead," have been debunked, but he's currently being kept alive on life support and some are saying his condition is going downhill. Crowds have gathered in Tahrir Square waiting for updates about his condition. The AP is reporting Mubarak is "being kept alive," on life support, while the BBC is saying he's "critically ill and may be close to death." A military source tells Reuters, "He is completely unconscious. He is using artificial respiration."
General Mamdouh Shaheen, of Egypt's Supreme Council of The Armed Forces, tells CNN that Mubarak "is not clinically dead as reported, but his health is deteriorating and he is in critical condition." He also says Mubarak, after getting revived and put on a respirator, also had a brain clot. We'll continue updating as the night goes on.
