The IAEA has been allowed to visit other nuclear sites in Iran since the 12-day war in 2025
Published June 25, 2026
VIENNA/TEHRAN, June 25, 2026 โ A fresh dispute has emerged between Iran and the United Nations’ nuclear watchdog after International Atomic Energy Agency (IAEA) Director General Rafael Grossi declared that inspections of Iranian nuclear facilities would resume under the framework of an interim U.S.-Iran agreement. Tehran, however, swiftly rejected the assertion, underscoring the fragile state of ongoing negotiations over Iran’s nuclear program.
Speaking during a visit to Japan, Grossi expressed confidence that IAEA inspectors would eventually regain access to Iranian nuclear sites, describing inspections as an essential component of any lasting agreement.
“The inspections will indeed take place,” Grossi said, adding that discussions were underway regarding the timing, procedures, and locations for future inspections. The comments came amid efforts to implement a recent U.S.-Iran memorandum that launched a 60-day negotiating period aimed at resolving disputes surrounding Iran’s nuclear activities.
Tehran’s Immediate Rebuttal
Iranian officials wasted little time challenging Grossi’s remarks.
Deputy Foreign Minister Kazem Gharibabadi stated that there are currently no plans to permit inspections of nuclear facilities damaged during previous U.S. and Israeli strikes, directly contradicting suggestions that access had already been agreed upon. According to Tehran, any discussion regarding inspections of sensitive sites can only occur after a final agreement is reached and after the United States takes concrete steps toward lifting sanctions.
Iran’s position represents the strongest rebuttal yet to claims from Western officials that inspection arrangements are effectively settled.
The disagreement highlights a growing gap between the optimistic public messaging coming from Washington and the IAEA, and Tehran’s insistence that major issues remain unresolved. Iranian officials argue that access to strategic nuclear facilities remains a negotiating tool rather than a commitment already granted.
Why the Inspections Matter
The IAEA has repeatedly sought access to Iran’s nuclear facilities and stockpiles of enriched uranium, particularly after military strikes and years of disputes over monitoring. The agency has expressed concern about the location and status of highly enriched uranium, some of which is enriched to levels close to weapons-grade material.
Western governments view inspections as critical for verifying that Iran’s nuclear program remains peaceful. Without renewed access, the IAEA says it cannot provide assurances regarding the condition of facilities or the whereabouts of nuclear materials.
Public Contradictions Complicate Diplomacy
The latest exchange has exposed a pattern of public contradictions surrounding the negotiations.
U.S. officials, including President Donald Trump, have repeatedly stated that Iran has agreed to extensive future inspections. Tehran has consistently denied that such commitments have been finalized, arguing that inspection arrangements remain contingent upon broader political and economic concessions.
Grossi’s intervention appears to align more closely with the U.S. interpretation of the agreement, while Iranian officials continue to insist that no automatic access has been granted. This divergence has raised questions about whether all parties share the same understanding of the interim accord.
