Iran Reiterates No Secret Nuclear Activity at Mount Fas
On Wednesday, Iran once again denied the existence of any secret underground nuclear facility at Mount Fas, located in the central region of the country. This statement comes in response to threats from U.S. President Donald Trump, who indicated that the American military might soon strike the area. Iranian Foreign Ministry spokesperson Ismail Baghaei took to the platform X to express that the United States' obsession with Mount Fas, where no nuclear activities are taking place, is merely a fabricated excuse to justify aggression, destruction, and sabotage. He emphasized that Iran's nuclear activities are fully disclosed to the International Atomic Energy Agency (IAEA).
During a press conference at the White House on Tuesday, Trump commented on Mount Fas, suggesting that the U.S. military is likely to strike this location very soon, adding that the Iranians 'cannot do anything about it.' Various American media outlets, including The Washington Post and The New York Times, reported in November 2025 that Iran had accelerated the construction of an underground nuclear site at Mount Fas, a claim that Tehran has previously denied.
Location and Strategic Importance of Mount Fas
Mount Fas is situated within the Zagros mountain range and rises approximately 1,600 meters high, comprised of hard granite rock, which makes it more fortified than known Iranian nuclear facilities, such as Fordow and Natanz. The site is located about 2 kilometers from the Natanz facility, which has been targeted by the U.S. in the past, specifically in June 2025, and was again struck following the outbreak of war in February 2025. Hazem Klass, a reporter for Alaraby TV in Tehran, noted that construction activities at Mount Fas have ramped up significantly over the past two years, although there is no confirmed information regarding the nature of the ongoing work.
IAEA inspectors were scheduled to visit the site before the outbreak of the 12-day war last year, as it was announced by Iran to be a new facility for uranium enrichment. However, the visit did not occur due to the onset of hostilities. IAEA Director General Rafael Grossi has previously mentioned the site, and former head of the Iranian Atomic Energy Organization Ali Akbar Salehi referred to the establishment of more fortified facilities. This development comes as Iran seeks to construct more secure nuclear installations after the Natanz facility faced two previous attacks, with experts estimating that the depth of the new site could exceed 150 meters beneath the granite rock.
