I read a lot of Arab countries don't like harboring Palestinian refugees for too long because 1) Israel never lets them back in. 2) They get mad that Israel isn't letting them back in and tend to blow up lots of shyt in the host countries.Even if the crossing is open you need a passport to leave, not everyone in palestine is a dual citizen. And Egypt is not visa free for palestinians. Palestinians can fly to south africa visa free but can't cross to egypt without one
