Palestinian President Yasser Arafat remained in a critical condition on Saturday, a senior aide said, despite a media report that he might have opened his eyes and talked to doctors. Nabil Abu Rdainah, a senior aide to Arafat, said the 75-year-old leader was still in a serious condition at the French military hospital where doctors have been unable to determine what is wrong with him. "The doctors say his condition is not irreversible. There is no change, he is still in a critical condition. The doctors still do not know what is wrong with him," Abu Rdainah said.
