Iran is strengthening its underground nuclear facilities as it prepares for crucial nuclear negotiations with the Trump administration. The Institute for Science and International Security (ISIS) reported that Iran is building a security perimeter around Mt. Kolang Gaz La, which is home to two significant underground tunnel complexes linked to the Natanz nuclear site. This development comes just ahead of the third round of talks set for this weekend.
Iran has firmly stated it will not halt uranium enrichment, despite the U.S. demand for a complete suspension. President Trump has indicated that military action could be a possibility if an agreement is not reached. The ongoing negotiations are seen as critical, with both sides looking for a path forward.
The new security perimeter around the mountain includes road grading and wall panels, creating a barrier that limits access to the entrances of the tunnels. This construction is complex due to the mountainous terrain and is supported by trenches that may be used for surveillance and communication systems.
While it appears that the tunnel complexes are not fully operational, some history is notable. One tunnel was built in 2007 and remained inactive for a decade before being reactivated five years ago. The other was developed to replace an underground facility that was destroyed in a 2020 explosion.
The International Atomic Energy Agency (IAEA) has not been allowed to inspect these tunnel complexes since 2007, raising concerns about Iran’s nuclear activities. IAEA Director Rafael Grossi recently urged Iran to clarify the purpose of the tunnels and the new security measures, but Iran dismissed his inquiries as irrelevant.
As Iran’s delegation arrives in Muscat, Oman, for the talks, there is cautious optimism. The discussions are expected to focus on technical details, and both sides have described previous meetings as productive. The U.S. technical team will be led by Michael Anton, while Iran’s delegation includes Kazem Gharibabadi, who has experience in past negotiations.
Iran’s Supreme Leader, Ayatollah Ali Khamenei, has shown signs of preparing his country for a potential agreement, despite previously opposing negotiations with the U.S. Foreign Minister Abbas Araghchi has indicated that while a comprehensive deal may be challenging within the 60-day timeframe set by Trump, an interim agreement could be feasible.
This weekend’s negotiations could be pivotal in shaping the future of Iran’s nuclear program and its relationship with the U.S. The world watches closely as both sides engage in these critical discussions.
