Camp David

WASHINGTON--Egyptian and Israeli negotiators opened new Mideast peace talks yesterday at Camp David with a joint pledge to complete a peace treaty as soon as possible.

Secretary of State Cyrus R. Vance headed the meetings. It is unknown whether United States proposals are responsible for the new talks.

In a joint statement Vance, Egyptian Prime Minister Mustafa Khalil and Israeli Prime Minister Moshe Dayan said they began the talks with a reaffirmation of "their determination to bend their best efforts toward successful completion of the negotiations as soon as possible."

A news blackout ordered by President Carter kept reporters and photographers out of the 147-acre retreat where the negotiations will be held in seclusion at least through the weekend.

Carter said the hoped the secrecy would facilitate a settlement.

State Department spokesman Hodding Carter said yesterday he could not reveal any of the proposals that may be under discussion.
