Excerpt from President Trump on AF1 about the 20 hostages:

"Getting them was… amazing actually, because WE WERE INVOLVED. And there were places you don't wanna know about… DEEP… DEEP, DEEP."

Very interesting. Sounds like American operators were helping Hamas to get the 'hostages' from deep below the surface.
