Sean Hannity is reporting from Israel this week, where he has gone inside a cavernous Hamas tunnel beneath Israel.

A lot of the cement used in the tunnels has been provided by Israel as aid to the Gaza Strip. Rather than using that cement for schools and homes, it has been used for the terror tunnels.
