Saudi Arabia will host the leaders of four Arab countries at a summit on 20 February to discuss Donald Trump's proposal for a US takeover of Gaza, a source with knowledge of the preparations said Friday.

The leaders of Egypt, Jordan, Qatar and the United Arab Emirates will attend the summit, which will take place ahead of an Arab League meeting in Cairo on 27 February on the same issue, the source said.

Speaking on condition of anonymity, another source said the president of the Palestinian Authority, Mahmud Abbas, would also attend.

Trump sparked a global outcry with his proposal for the United States to take over the Gaza Strip and to move more than two million Palestinians out of the territory, citing Egypt or Jordan as possible destinations.

Israeli Prime Minister Benjamin Netanyahu has since suggested Saudi Arabia could also host Palestinians, in remarks that drew condemnation from the Arab world, but which some Israeli media characterized as a joke.

Arab countries have come together in a rare united front, outraged by the idea of displacing the Palestinians en masse.

For Palestinians, any forced displacement evokes memories of the "Nakba", or catastrophe — the mass displacement of their ancestors during Israel's creation in 1948.

But Trump has threatened to cut off a vital aid lifeline to long-standing allies Jordan and Egypt should they refuse to come on board.

Jordan is already home to more than two million Palestinian refugees. More than half of the country's population of 11 million is of Palestinian origin.

Egypt put forward its own proposal for the reconstruction of Gaza under a framework that would allow for the Palestinians to remain in the territory.
