Satellite Images Show Accelerated Construction at Suspected Iranian Nuclear Site
Satellite imagery analyzed by a US research center reveals a significant acceleration in construction activities at a fortified Iranian site deep within Mount Kolan, near Natanz, during 2026. Western intelligence agencies suspect Tehran is developing an undeclared uranium enrichment facility at this location. The latest images, taken on August 9, show intensified work on fortifying tunnel entrances and the internal road network.
Experts from the Center for Strategic and International Studies (CSIS), a Washington-based think tank, analyzed satellite photos spanning six years. They concluded that the activity on the roads within Mount Kolan in 2026 surpasses any previously recorded levels since the site's inception. The experts noted a clear increase in construction, including the reinforcement and elevation of tunnel entrances, paving of internal roads, enhancement of areas around the entrances, and the clearing of excavation debris.
However, the CSIS experts stated they could neither confirm nor deny Israeli intelligence reports suggesting that Iran has transferred centrifuges to the site. This location was previously threatened with a strike by then-US President Donald Trump in July, as part of Washington's stated aim to dismantle Iran's nuclear program. Trump's threat has not yet been acted upon.
The International Atomic Energy Agency (IAEA) has requested information from Tehran regarding Mount Kolan and access to the site, but according to reports cited by CSIS, Iran has not complied. The experts highlighted the difficulty of destroying the fortified facility, which is embedded within a granite mass at a considerable depth, even with the most powerful non-nuclear US munitions.
The ongoing conflict between the United States and Iran has entered its seventh month. On Wednesday, Tehran launched new attacks on US targets in the region, reportedly in retaliation for US strikes on Iranian oil tankers, indicating a further escalation of military tensions.
