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

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

Speaking on condition of anonymity, another source said Palestinian President Mahmoud Abbas would also attend.

Trump sparked a global outcry with his proposal for the US to “take over” the Gaza Strip and to move more than 2mn Palestinians out of the war-devastated territory, citing Egypt or Jordan as possible destinations.

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.
