THURMONT, Md. (AP) _ President Clinton flew to Camp David on Tuesday to launch a high-stakes drive for peace between Israel and the Palestinians, cautioning both sides that ``there can be no success without principled compromise.''

Clinton said Israeli Prime Minister Ehud Barak and Palestinian leader Yasser Arafat ``face profound and wrenching questions.''

``The road to peace, as always, is a two-way street,'' the president said. ``Both leaders feel the weight of history but both, I believe, recognize this is a moment in history which they can seize. We have an opportunity to bring about a just and enduring end to the Israeli-Palestinian conflict. That is the key to lasting peace in the entire Middle East.''

He spoke at the White House before boarding his helicopter for the flight to Camp David.
