US President Donald Trump said on Thursday that Israel would hand over Gaza to the United States after fighting was over and the enclave's population was already resettled elsewhere, which he said meant no US troops would be needed on the ground.

A day after worldwide condemnation of Trump's announcement that he aimed to take over and develop the Gaza Strip into the “Riviera of the Middle East”, Israel ordered its army to prepare to allow the “voluntary departure” of Gaza's residents.

Trump, who had previously declined to rule out deploying US troops to Gaza, clarified his plans in comments on his Truth Social web platform.

“The Gaza Strip would be turned over to the United States by Israel at the conclusion of fighting,” he said. Palestinians “would have already been resettled in far safer and more beautiful communities, with new and modern homes, in the region.”

“No soldiers by the US would be needed!” he said.

Earlier Israel’s Defence Minister said he had ordered the army to prepare a plan to allow residents who wished to leave to exit Gaza voluntarily.

“I welcome President Trump’s bold plan, Gaza residents should be allowed the freedom to leave and emigrate, as is the norm around the world,” Katz said on X.

Katz said his plan would include exit options via land crossings, as well as special arrangements for departure by sea and air.

Trump’s unexpected announcement on Wednesday, which has sparked anger around the Middle East, came as Israel and Hamas were expected to begin talks on the second round of a fragile ceasefire plan to end almost 16 months of fighting in Gaza.

Regional heavyweight Saudi Arabia rejected the proposal outright and Jordan's King Abdullah, who will meet Trump at the White House next week, said on Wednesday he rejected any attempts to annex land and displace Palestinians.

Hamas official Basem Naim accused Katz of trying to cover up “for a state that has failed to achieve any of its objectives in the war on Gaza”, and said Palestinians are too attached to their land to ever leave.

Displacement of Palestinians has been one of the most sensitive issues in the Middle East for decades. Forced or coerced displacement of a population under military occupation is a war crime, banned under the 1949 Geneva Conventions.

Israeli strikes which killed tens of thousands of people over the past 16 months have forced Palestinians to repeatedly move around within Gaza, seeking safety.

But many say they will never leave the enclave because they fear permanent displacement, like the “Nakba”, or catastrophe, when hundreds of thousands were dispossessed from homes in the war at the birth of the state of Israel in 1948.

Katz said countries who have opposed Israel’s military operations in Gaza should take in the Palestinians.

“Countries like Spain, Ireland, Norway, and others, which have levelled accusations and false claims against Israel over its actions in Gaza, are legally obligated to allow any Gaza resident to enter their territories,” he said.
