DELEGATES OF FATAH CONVENE

Hundreds of delegates from Fatah, the main PLO faction, have arrived in Tunis for a congress that will review Yasser Arafat's peace moves. The meeting is expected to open in the next few days, possibly Thursday.

A substantial hardline group in Fatah is challenging PLO Chairman Arafat's policy of relying on diplomatic methods to bring about a Palestinian state in the Israeli-occupied West Bank and Gaza Strip.

Arafat has already renounced terrorism and recognized Israel's right to exist in its pre-1967 borders.
