Ahmad Tibi, the lawmaker close to Abbas, told Israeli Army Radio that Abbas could be discharged as early as Tuesday. He did not elaborate on Abbas' condition nor say why he thought Abbas was expected to be released.
Palestinian officials on Sunday had said that Abbas has pneumonia and was on a respirator, receiving antibiotics intravenously. They said he was conscious and lucid.
Abbas, who is a heavy smoker and overweight, has a long history of health issues, ranging from heart trouble to a bout with prostate cancer a decade ago. Two years ago, he underwent an emergency heart procedure after suffering exhaustion and chest pains.
More recently, a cardiologist moved into the presidential compound in Ramallah to monitor the longtime leader after a mysterious hospital visit in the United States, following Abbas' address to the United Nations Security Council in which he appeared weak.
Abbas, who insists he is fine, has refused to designate a successor. But after more than a decade of avoiding discussion of the post-Abbas era, Palestinian officials acknowledge that they are concerned, and potential successors are quietly jockeying for position.
Abbas took over as a caretaker leader following the death of Palestinian leader Yasser Arafat in 2004, and was elected for what was supposed to be a five-year term the following year.
He has remained in firm control since then, governing parts of the West Bank, while a political split with rival Hamas the Palestinian militant group that in 2007 seized the Gaza Strip has prevented new elections.
