Iran's suspension of IAEA cooperation since the June 2025 strikes has blocked inspectors from Fordow, Natanz, and Isfahan, leaving the agency unable to verify enriched uranium stockpiles or centrifuge status at these enrichment sites. Tehran links any resumption of access to sanctions relief and broader diplomatic progress, as signaled by Foreign Minister Abbas Araghchi in late September 2026 private talks. The IAEA Board referred Iran to the UN Security Council in September 2026 over safeguards noncompliance, while satellite imagery shows ongoing activity at related locations like Pickaxe Mountain. Limited inspections have occurred at unaffected sites such as Bushehr, but key facilities remain off-limits pending negotiated protocols or external pressure. Upcoming diplomatic contacts and any sanctions discussions could influence timelines for resumed verification.
