Don't need a nuke that big. Operation Plowshare showed that a 100kt nuke in a 1000m deep bore hole will obliterate tunnels for miles and create a nice swimming pool for Gaza. I say nuke the tunnels or flood them.

Peaceful nuclear explosions/nuclear engineering can solve this problem with minimal casualties:

Yeah, but this was based upon no bore hole being present. Big difference. 🙂
