Israeli and American intelligence officials said Iran is digging a vast tunnel network south of the Natanz nuclear production site, in what they believe is Tehran’s biggest effort to construct new nuclear facilities so deep in the mountains that withstand bunker-busting bombs and cyberattack, the New York Times revealed Friday.
It said that although the construction is evident on satellite photographs and has been monitored by groups that track the proliferation of new nuclear facilities, Biden administration officials have never talked about it in public and Israel’s defense minister Benny Gantz has mentioned it just once, in a single sentence in a speech last month.
