President Bush on Saturday called for "fresh thinking" to combat the daunting challenges that remain in the Middle East a decade after the historic accord between Israel and Egypt.

Bush said that the treaty that ended more than 30 years of war between the two countries was "the product of vision, statesmanship, courage and persistence on the part of all the participants."Bush was spending the weekend with his family at Camp David, the Maryland presidential retreat where Israel's Menachem Begin and Egyptian President Anwar Sadat worked out the historic agreement with then-President Jimmy Carter.

"Recognizing the historic achievement of 10 years ago, however, turns our minds toward the still more daunting challenges ahead," the president said. "We need to complete the work they began. We must commit ourselves, as Anwar Sadat and Menachem Begin did, to fresh thinking."

Bush said there is "growing understanding that a settlement can be reached which both satisfies Israel's security needs and addresses the legitimate political rights of the Palestininans."

Bush and his wife Barbara were spending the Easter holiday with three of their five children and six grandchildren.

They were to attend Easter services at Camp David with base personnel, and then dine on an Easter dinner of turkey, sweet potatoes and blueberry pie.
