IAEA Urges Immediate Access to Iranian Nuclear Sites Amid Proliferation Concerns

Iran’s reduced cooperation with the UN nuclear agency raises alarms over verification of nuclear materials.

The International Atomic Energy Agency (IAEA) has issued an urgent call for immediate access to Iran’s nuclear facilities to verify materials and ensure non-proliferation safeguards.

In a quarterly report reviewed by news agencies on Tuesday, the UN nuclear watchdog stated that its inability to obtain information about nuclear materials and access to verification facilities constitutes a significant proliferation concern.

The United States has framed its military operations that began in March as aimed at preventing Iran from acquiring a nuclear weapon—a goal Tehran continues to reject. Yet Iran has effectively redirected attention toward control of the strategically vital Strait of Hormuz.

The IAEA report specifically highlighted concerns regarding restricted access to the Isfahan plant, which has been targeted multiple times by both the US and Israel over the past year.

In the report, IAEA Director General Rafael Grossi expressed strong conviction that long-standing challenges and recurring crises on these matters must be resolved through a durable, verifiable diplomatic agreement.

Iran has indicated that access to sites affected by military strikes would need to be coordinated through special arrangements.

The head of Iran’s Atomic Energy Organization, Mohammad Eslami, stated on August 26 that the IAEA “cannot seek to inspect these centers until it develops specific criteria and protocols for inspecting sites targeted by military attacks.”

Tehran had suspended cooperation with the UN nuclear agency following US and Israeli attacks on Iranian nuclear sites in June 2025, later announcing in September 2025 that it would permit inspectors to return. However, access to the bombed nuclear facilities has not yet been granted. Despite former US President Donald Trump’s claims last year that the US had destroyed the facilities and neutralized Iran’s nuclear program, Iran’s enriched uranium stockpiles remain unverified.

Iran has consistently denied any military ambitions related to its nuclear program, emphasizing its right to pursue nuclear technology for civilian purposes.

Nevertheless, the IAEA has previously noted that the level of uranium enrichment in Iran’s reserves exceeds what is required for civilian use, though it remains below weapons-grade specifications.
