The Director General of the International Atomic Energy Agency (IAEA), Rafael Grossi, expressed "concern" on Monday regarding Iran's failure to provide clarifications about sites suspected to have previously unreported nuclear activities, while Tehran continues to accumulate its stockpile of enriched uranium.
An IAEA report stated that the Director General is "worried about the lack of results from technical talks between the agency and Iran," referencing discussions about these sites with Iranian officials. These talks, which began in April, aimed to clarify the potential presence of nuclear materials at several locations. The Vienna-based agency indicated that "the current locations of these sites are unknown to the agency."
In its previous report in February, the agency mentioned one of these sites without naming it, likely referring to a storage facility in the Torquzabad region in Tehran. The current report highlights a total of three sites, noting a fourth site where "Iran has not responded to the agency's questions."
The report, set to be discussed by the agency's Board of Governors next week, also focuses on the stockpile of low-enriched uranium that Tehran has accumulated, which now exceeds the permitted limit by approximately 16 times under the 2015 international agreement. The agency estimates that this stockpile has reached 3,241 kilograms, while the allowed ceiling is 300 kilograms. In its previous report, the agency noted that the stockpile was at 2,967 kilograms.
Since 2019, Iran has gradually abandoned its nuclear commitments in response to the reimposition of U.S. sanctions by former President Donald Trump. Negotiations in Vienna continue in an attempt to bring the United States back into the aforementioned agreement aimed at preventing the Islamic Republic from acquiring nuclear weapons.
