First thought was Al-Aqasa...
Wonder what’s under That ???
Jordan has been in control of Al Aqasa for decades. I doubt things have been added.
But, they are excavating areas of the site with little of no concern for artifacts.
Muslims deny that Jews were there long long ago. Of course there is a lot of evidence it is true that Jews built the first structure there.
On the subject of tunnels in Gaza strip, I’m sure that since US denied them bunker buster bombs, they simply figured out another way to get the job done.
