The White House says momentum is building in part because Arab and Muslim states are demonstrating a renewed focus on resolving the broader, decades-long Israeli-Palestinian conflict and, in some cases, deepening relations with the United States.

“I think you are going to have tremendous success and Gaza is going to be rebuilt,” Mr Trump said Friday.

“And you have some very wealthy countries, as you know, over there. It would take a small fraction of their wealth to do that. And I think they want to do it.”

The first phase of the ceasefire agreement calls for the release of the final 48 hostages held by Hamas, including about 20 believed to be alive; the release of hundreds of Palestinian prisoners held by Israel; a surge of humanitarian aid to Gaza; and a partial pullback by Israeli forces from Gaza’s main cities.

Israeli troops on Friday finished withdrawing from parts of Gaza, triggering a 72-hour countdown under the deal for Hamas to release the Israeli hostages, potentially while Mr Trump is on the ground there. He said he expected their return to be completed on Monday or Tuesday.

Mr Trump will visit Israel first to meet hostage families and address the Knesset, or parliament, an honour last extended to President George W Bush during a visit in 2008.
