Foreign Minister Moshe Dayan will hear Israel's delegation to the Israeli-Egyptian peace talks in Washington on Oct. 12, and will be accompanied by Deputy Prime Minister Yigael Yadin and Interior Minister Josef Burg, government sources said last night.

Israel's Cabinet will meet Sunday to formally appoint the delegation, which is expected to include Defense Minister Ezer Weizman at some point.

Dayan plans to leave ahead of the others to address the U.N. General Assembly in New York on Monday, and Weizman is expected to join the talks when they reach discussions of military matters.

Israeli officials expect the early stages of the conference to focus on political matters, with considerable attention on links between the bilateral Israeli-Egyptian frameworks for peace and the larger Middle East framework that deals with the future of the occupied West Bank and Gaza Strip.

Prime Minister Menachem Begin has said that the talks could be completed and a document signed within "two weeks, if not in a few days."

Egyptian Foreign Ministry Officials have said they would like to have a treaty-signing ceremony on Nov. 19, the first anniversary of President Anwar Sadat's visit to Jerusalem.

Among the unresolved details are: The precise terms of demilitarization of the Sinai Peninsula and a schedule for withdrawal of Israeli troops and dismantling of Jewish settlements there; defining the line between El Arish in the north and Ras Muhammed in the south, to which Israeli forces will withdraw in three to nine months after the signing; deployment of early warning system; construction of a road linking the Sinai to Jordan, and establishment of air traffic lanes, customs controls, shipping routes, exchanges of embassies and other details of normalizing relations between the two countries.

Arab diplomats in Bahrain said a call by Iraq for an urgent Arab summit to discuss the Camp David accords has received the support of Jordan, Saudi Arabia, Kuwait, Bahrain, the United Arab Emirates, Oatar and Oman. The Persian Gulf states were said to be confident that Egypt would also attend, although the objective would be to dissuade Egypt from signing a separate peace treaty with Israel.

Roving U.S. Ambassador Alfred Atherton wound up a tour of Arab states to explain the Camp David accords, leaving Morocco for Western Europe, where he has a similar assignment.
