Egyptians, Israelis Start Talks

WASHINGTON--Egyptian and Israeli representatives met in Washington yesterday to open treaty negotiations that President Carter said must ultimately be broadened to include all Arab parties to the Middle East conflict.

The negotiations will deal with details of Israeli withdrawal from the Sinai desert, security arrangements and an exchange of ambassadors.

The two nations hope to complete a peace treaty within two months.

At an opening ceremony at the White House, President Carter responded to criticism from many Arab countries that they have been excluded from negotiations. He stressed the goal of making "peace and dignity a reality for all the people of the Middle East."

Carter specifically invited Jordan and Palestinians living in the West Bank and Gaza to join the peace process.

A statement issued at the end of the day said "good progress" was made, both in separate meetings with Secretary of State Cyrus R. Vance and in three-way talks.

The negotiations, which are expected to last for up to two weeks, resume this morning.
