An analysis of new satellite imagery indicates that Iran is strengthening an underground complex near one of its nuclear sites.

The activity comes as talks continue between Iranian and U.S. officials, while President Donald Trump has threatened new military action if no agreement is reached on Iran’s nuclear program.

The images, first analyzed by the Institute for Science and International Security (ISIS), show reinforced tunnel entrances at Mount Kolang Gaz La, also known as Mount Kazma.

Experts say the facility may be designed to protect uranium enrichment activities or key equipment, but its exact purpose and operational status remain unclear.

Iran insists that its nuclear program is entirely peaceful and not aimed at developing nuclear weapons.

However, in June 2025, during a 12-day conflict between Israel and Iran, Trump said Iran was only a month away from obtaining a nuclear weapon and ordered airstrikes on three underground nuclear facilities.
