BONN, JAN. 25 -- Egyptian President Hosni Mubarak called today for an end to violence in the Middle East and for an international conference on peace in the region. He is on a six-nation tour to promote peace proposals he made last week.

"The only option toward the stabilization of the situation is a peace conference," he told reporters before leaving for London. He is to meet with Prime Minister Margaret Thatcher on Tuesday and fly to Washington for talks with President Reagan. On his way home, he will visit France, Morocco and Italy.

During the four-hour stop in Bonn, he made no direct reference to violence between Israeli forces and Palestinians in the Israeli-occupied West Bank and Gaza Strip.

"It is only through peace that we can raise our living standards, and make for better lives for Israelis as well as Arabs," Mubarak said.

He spent two hours with Chancellor Helmut Kohl, who said later that West Germany supports Mubarak's peace initiative.

Mubarak's plan involves a suspension of Palestinian unrest in the West Bank and Gaza strip for six months and a halt to the building of Israeli settlements in the occupied territories in order to create the climate for an international conference.

Israel's coalition government has split on the Mubarak plan.
