Indicating a possible serious split in the PLO's top ranks, a member of its governing body says Yasser Arafat's recognition of Israel and renunciation of terrorism represent "Arafat's personal opinion." Mustafa Zibri, a member of the PLO executive committee, said Monday that the PLO chairman's statements last week were "incompatible with the resolutions of the latest Palestine National Council meeting." The council, the PLO's parliament-in-exile, met in Algeria last month to declare an independent Palestinian state. It indirectly B recognized Israel's existence and condemned terrorism, but did not go far enough to gain U.S. recognition.
