That’s the rumor going around in Israel, that they will be transferred underground through Egypt with every rumor there is always a lil bit of truth to it how much no idea
“That’s the rumor going around in Israel”
Weird rumor. Would require a lot of help from Egypt (not gonna happen). Without Egyptian help I don’t see how. In secret overland, too long a trip too many countries to cross. By sea pretty much the same problem.
You would need some kind of James Bond type scenario with Egyptian security being bribed or otherwise made to look the other way and then an Iranian plane landing in Sinai.
American and Israeli intelligence would pick up the plane.
