Former Israeli Prime Minister Ariel Sharon was in critical condition  Thursday as his vital organs are failing, a hospital official said.
Ze'ev Rothstein, director of Sheba Medical Center at Tel Hashomer near Tel Aviv, said Sharon, reportedly suffering from serious kidney failure, was not on dialysis but receiving antibiotics because of numerous infections, the Jerusalem Post reported.
"He's getting all the treatment necessary," Rothstein said.
Sharon, 85, has experienced "a serious deterioration in his health" during the past two days , Rothstein said.
Sheba Medical Center spokesman Amir Marom said Sharon's condition had been worsening during the past several days. When asked what could be expected in the coming days, he said, "Only God knows."
"We have hope, we always have hope," Omri Sharon, a former lawmaker, told the Post from the hospital.
Sharon had been undergoing dialysis for kidney failure to prevent the rest of his organs from failing, the Post said. He underwent surgery a month and a half ago to treat an infection caused by kidney failure.
Sharon has been in a coma since his Jan. 4, 2006, stroke.
Sharon, one of Israel's legendary politicians and military leaders , played a key role in military victories in both the 1967 Six Day War and in the 1973 Yom Kippur War.
In the political realm, he was the father of the Likud and Kadima parties. Sharon held several Cabinet posts, including Defense, Construction and Housing, and the Foreign ministries. He was elected prime minister in 2001.
