JERUSALEM, Oct. 28 (Xinhuanet) -- Israel guarantees Palestinian leader Yasser Arafat's safe return to the West Bank if he needs to go abroad for medical treatment, Israeli Prime Minister Ariel Sharon's senior adviser Dov Weisglass said Thursday.

    Israel had previously given its permission for Arafat to be transferred to any hospital in the world.

    Arafat was earlier expected to be transferred from his Muqata headquarters in the West Bank city of Ramallah to a local hospital as Palestinian sources said he was in serious but stable condition.   Israeli media said Palestinian officials were also considering moving him to hospitals abroad, such as in Jordan or Egypt.   A Jordanian government spokesman told Israel Radio that it would allow Arafat to be treated in the country, but only if Israel guaranteed that he could return to the territories.

    Palestinian sources said on Wednesday night that Arafat was in critical condition and a team of doctors in his Ramallah headquarters were fighting for his life.

    On Thursday morning, Arafat's aides said the Palestinian National Authority Chairman sent a message to his people saying that his condition was good and there was no reason to worry about him.  Enditem
