The U.S. and Israel have reached out to officials of three East African governments to discuss using their territories as potential destinations for moving Palestinians uprooted from the Gaza Strip under President Donald Trump’s proposed postwar plan, American and Israeli officials told The Associated Press.

The contacts with Sudan, Somalia and the breakaway region of Somalia known as Somaliland reflect the determination by the U.S. and Israel to press ahead with a plan that has been widely condemned and raised serious legal and moral issues. Because all three places are poor, and in some cases wracked by violence, the proposal also casts doubt on Trump’s stated goal of resettling Gaza’s Palestinians in a “beautiful area.”

Officials from Sudan said they have rejected overtures from the U.S., while officials from Somalia and Somaliland told The Associated Press that they were not aware of any contacts.

Under Trump’s plan, Gaza’s more than 2 million people would be permanently sent elsewhere. He has proposed the U.S. would take ownership of the territory, oversee a lengthy cleanup process and develop it as a real estate project.

The idea of a mass transfer of Palestinians was once considered a fantasy of Israel’s ultranationalist fringe. But since Trump presented the idea at a White House meeting last month, Israeli Prime Minister Benjamin Netanyahu has hailed it as a “ bold vision.”

Palestinians in Gaza have rejected the proposal and dismiss Israeli claims that the departures would be voluntary. Arab nations have expressed vehement opposition and offered an alternative reconstruction plan that would leave the Palestinians in place. Rights groups have said forcing or pressuring the Palestinians to leave could be a potential war crime.

Speaking on condition of anonymity to discuss a secret diplomatic initiative, U.S. and Israeli officials confirmed the contacts with Somalia and Somaliland, while the Americans confirmed Sudan as well. They said it was unclear how much progress the efforts made or at what level the discussions took place.

Separate outreach from the U.S. and Israel to the three potential destinations began last month, days after Trump floated the Gaza plan alongside Netanyahu, according to the U.S. officials, who said that Israel was taking the lead in the discussions.

Israel and the U.S. have a variety of incentives — financial, diplomatic and security — to offer these potential partners. It is a formula that Trump used five years ago when he brokered the Abraham Accords — a series of mutually beneficial diplomatic accords between Israel and four Arab countries.

The White House declined to comment on the outreach efforts.

The offices of Netanyahu and Ron Dermer, the Israeli Cabinet minister and Netanyahu confidant who has been leading Israel’s postwar planning, also had no comment.

But Finance Minister Bezalel Smotrich, a longtime advocate of what he calls “voluntary” emigration of Palestinians, said this week that Israel is working to identify countries to take in Palestinians. He also said Israel is preparing a “very large emigration department” within its Defense Ministry.
