Palestinians make demands before talks AMMAN, Jordan, Jan. 2 (UPI) -- Some Palestinian factions are criticizing the Palestinian Authority for agreeing to meet with Israelis in Jordan this week. Hamas, one of several Palestinian groups upset the PA's chief negotiator will hold direct talks with his Israeli counterpart, called for the PA to boycott the Amman meeting Tuesday. The Popular Front for the Liberation of Palestine condemned the talks as a "grave mistake that would encourage occupation to pursue its practices" against Palestinians. There was no comment from Israeli negotiators, The Jerusalem Post said. Chief Palestinian negotiator Saeb Erekat said Sunday Israel's cessation of settlement construction and acceptance of the pre-1967 lines pre-conditions for a two-state solution. Erekat, Israeli envoy Yitzhak Molcho and representative of the Middle East Quartet are to meet first in Amman, followed by a second meeting between just Palestinian and Israeli officials. The Quartet consist of the United Nations, the United States, the European Union and Russia. Acceptance by Israel of the Palestinian Authority demands would pave the way for the resumption of real and serious negotiations between the two sides, Erekat said. The meeting in Jordan should "commit" Israel to "international legitimacy, including the road map for peace, which calls for a freeze of construction in the settlements," Erekat said. "We hope the Israeli government will realize the significance of the Jordanian invitation to hold talks in Amman," he said.
