Palestinian opposition group supporter Isam — not his real name — said: “Trump has suggested we go to Egypt or Jordan but we’d be swapping one hell for another.
Teacher Isam, 29, said Palestinians currently pay more than £5,000 just to cross to Egypt but do not stay there as they are badly treated.
He added: “So if the Trump plan gets Gazans to Egypt for free they’ll take up the offer and keep moving west, to Istanbul then Europe.
Isam said Hamas was regrouping in the ceasefire, with militiamen seizing aid and food and reselling it to locals at inflated prices.
But the idea is said to be likely to start an exodus of hundreds of thousands through Arab countries and eventually to Europe.
