Iran Accelerates Secret Expansion of Nuclear Facilities in the Zagros Mountain Range

Chas Pravdy - 27 September 2025 05:34

Recent satellite image analyses reveal that Tehran is actively expanding its nuclear capabilities, focusing on underground facilities hidden within the Zagros mountain massif.

This strategic move indicates Iran’s effort to bolster its position despite official statements about a moratorium on uranium enrichment.

Observations show that Iranian engineers are not abandoning their construction efforts—instead, they are intensifying work by reinforcing key points to protect sites from potential airstrikes, especially near Mount Kirka, located close to the Natanz nuclear complex.Sources familiar with independent intelligence assessments report increased security measures: perimeter walls have been extended, tunnels fortified, and excavation activities have surged, indicating extensive underground development.

Meanwhile, IAEA inspectors have yet to gain access to the site, and the agency’s director Rafael Grossi has stated that Iran has refused to answer questions regarding this location.Experts estimate that underground chambers at Mount Kirka could be situated at depths up to 100 meters, making them even more protected than the Fardo facility.

Although Iran stated in 2020 that this site would host centrifuge manufacturing, the current size and tunnel depths raise doubts among specialists.

Analysts suggest this complex might be used for clandestine uranium enrichment or as a secure storage of uranium reserves nearing weapons-grade levels.Three independent experts analyzing satellite imagery have identified key signs of activity: increased security perimeter, new roads and reinforced entrances, and rising quantities of excavated rock.

The movement of heavy machinery indicates ongoing and possibly expanding underground construction.

International observers, including U.S.

officials and IAEA monitors, continue to scrutinize and warn about Iran’s potential nuclear escalation.Overall, this development underscores the ongoing tension surrounding Iran’s nuclear ambitions and the global community’s efforts to monitor and prevent the proliferation of nuclear weapons.

The situation remains dynamic, with further developments likely as Tehran seeks to quietly enhance its nuclear infrastructure.
