Exiled former Zairian dictator Mobutu Sese Seko, suffering from advanced prostate cancer, checked into a Moroccan hospital after France refused to allow him entry for medical treatment, said his son, Nzanga Mobutu. A hospital official in the Moroccan capital, Rabat, said Mobutu checked into the hospital but refused to give any other information. Nzanga Mobutu said his father was "doing fine" and would return to the luxury hotel in Tangier where he has been staying. Mobutu had surgery in August in Switzerland and since then has undergone repeated treatment for prostate cancer. He has been in Morocco since being chased by rebel forces from Zaire, now renamed Congo.
