IAEA Warns of Proliferation Risks as Iran Blocks Nuclear Access

The International Atomic Energy Agency is urging Iran to take incremental technical steps to allow inspectors back into key nuclear facilities to prevent nuclear proliferation. In a confidential report, the UN watchdog highlighted a critical lack of information regarding the Isfahan Fuel Enrichment Plant, an underground facility declared by Iran in June 2025. The agency reports it does not know the plant's exact location, its safeguards status, or whether it contains nuclear material.

Inspectors have been largely blocked from Iranian sites since June 2025, following a 12-day bombing campaign by Israel and the United States that damaged several enrichment sites. While inspectors visited the Bushehr nuclear plant in September, the agency cannot confirm that declared nuclear material has not been diverted from peaceful activities. Consequently, the IAEA board referred Iran to the UN Security Council in September for non-compliance with reporting obligations for the first time in 20 years.

Parallel to these concerns, Iran is reviewing mediator proposals during talks with the United States in Doha, Qatar. However, Iranian officials maintain they will not show flexibility on their nuclear program or reopen the Strait of Hormuz until the United States lifts a naval blockade on Iranian ports and meets all other Iranian conditions.
