Iran Ramps Up Activity at Suspected Nuclear Site After Trump Threats

Iran has significantly accelerated construction and preparatory work at a subterranean site identified as "Mount Makran," believed to be linked to its nuclear program, according to a CNN report citing analysis of satellite imagery. Experts from the Center for Strategic and International Studies (CSIS) observed a marked increase in activity over the past year, including efforts to reinforce tunnel entrances, pave internal roads, and clear excavated earth.

The site, located in the Zagros Mountains near the Natanz nuclear facility, is considered highly sensitive. The CSIS analysis, based on satellite photos spanning six years, suggests the underground facility may be exceptionally deep and heavily fortified, potentially posing a challenge even for bunker-buster munitions.

This surge in activity follows recent threats from then-U.S. President Donald Trump to attack the site, which Western intelligence has suggested could be used for uranium enrichment or storing sensitive nuclear materials. While CSIS researchers caution that satellite imagery alone cannot definitively determine the purpose of the ongoing work, the pattern indicates a shift from excavation to reinforcement and internal construction amidst heightened tensions over Iran's nuclear ambitions.
