LUXOR, Egypt — Secretary of State Condoleezza Rice will attend a three-way summit with the Israeli and Palestinian leaders in the coming weeks in an effort to boost Mideast peace efforts, U.S. officials said today.

The announcement came shortly after Rice wrapped up a brief visit to Israel and the West Bank.

A senior U.S. official in Rice's delegation said the "trilateral meeting" will be aimed at "having a conversation about the political horizon leading to the establishment of a Palestinian state."

He spoke on condition of anonymity because he was not authorized to speak to reporters on the record.

Israeli Prime Minister Ehud Olmert's spokeswoman, Miri Eisin, confirmed the Israeli leader had agreed "in principle" to attend the summit. But she said no date or place had been set.

The U.S. official said the meeting would likely take place in the next three or four weeks somewhere in the Middle East.

Palestinian officials were not immediately available for comment.

On a related front Rice is asking Arab allies to help support the fragile government in Iraq, on whose success much of President Bush's new plan to turn the war around will depend.

The Arab leaders are eager for the U.S. to take a larger role in brokering peace between Israel, the Palestinians and others in the region.

Rice was meeting diplomats and leaders in Egypt and Saudi Arabia today, a day after a similar session in Jordan.
