Iran building nuclear facility deep enough that US bombs would likely be incapable of destroying it: Report

Iran is continuing work on a nuclear facility that is so deep, experts fear the convention U.S. weapons may not be powerful enough to destroy them with airstrikes.

The comments come after satellite imagery, taken in April by Planet Labs PBC and analyzed by the AP, show workers digging tunnels near a peak of the Zagros Mountains in central Iran close to the Natanz nuclear site, a site long watched by international nuclear observers that has come under repeated sabotage attacks Iran has blamed on Israel.

The satellite imagery of the site, which is protected by fencing, anti-aircraft batteries, and Iran’s paramilitary Revolutionary Guard, shows four entrances being dug into the mountainside. Analysts are able to estimate the depth of the entrances by looking at the size of the spoil piles and other satellite data, which they say now indicated the facility is at depths of 260 and 328 feet.
