CAIRO (AP) — Israel said on Thursday it has begun preparations for the departure of large numbers of Palestinians from the Gaza Strip in line with President Donald Trump’s plan for the territory. Officials meanwhile said Egypt has launched an diplomatic blitz behind the scenes to try and head off the plan.

The president refused to back down from his proposal for the U.S. to oversee the war-ravaged coastal enclave — and send the Palestinians who live there somewhere else.

Israel prepares for potential mass Palestinian exodus from Gaza, sparking international concern and diplomatic pushback.
