The United Nations nuclear watchdog has identified a new underground uranium enrichment facility in Isfahan, Iran, sparking fresh international concern over Tehran’s nuclear ambitions.
Director General of the , , revealed that the agency has yet to inspect the newly discovered site, leaving critical questions unanswered about its purpose and level of development.
Speaking while in Washington for high-level engagements, including meetings with officials linked to the , Grossi said the facility is located deep underground but remains inaccessible to inspectors.
“It is underground, but we haven’t visited it yet,” Grossi said, emphasizing the uncertainty surrounding the site.
Inspection Delayed, Questions Mount
The IAEA had planned to visit the facility, but the inspection was cancelled, preventing experts from verifying whether the complex is operational or still under construction.
Grossi noted that it is unclear whether the site is “simply an empty hall” or already housing centrifuges used to enrich uranium — a key process in developing nuclear fuel or weapons.
“There are many questions that we will only elucidate when we are able to go back,” he added.
Rising Uranium Stockpile Raises Alarm
According to IAEA estimates, currently possesses approximately 440 kilograms of uranium enriched to 60 percent purity — a level far beyond what is required for civilian nuclear energy.
Experts warn that this stockpile could be further enriched to 90 percent, the threshold considered weapons-grade, if Iran chose to accelerate its program.
The discovery of the underground facility in — already known as a hub for Iran’s nuclear activities — is likely to intensify global scrutiny and diplomatic tensions.
Global Implications
The development comes at a time of heightened sensitivity around Iran’s nuclear program, with world powers closely monitoring any signs of advancement toward weapons capability.
Without immediate access to the site, the IAEA’s ability to independently verify Iran’s activities remains limited — a situation that could further strain international trust and complicate ongoing diplomatic efforts.
As inspectors await clearance to revisit the facility, the world is left watching closely, with the stakes around nuclear proliferation higher than ever.
