Urgent need for access to Iranian sites, cautions UN nuclear watchdog

The IAEA said lack of information and access to facilities to verify Iran’s nuclear material is a proliferation concern.The International Atomic Energy Agency (IAEA) has called for “utmost urgency” to address the lack of access to Iran’s nuclear sites.In a quarterly report seen by news agencies on Tuesday, the United Nations nuclear watchdog labelled its “lack of information about this nuclear material and access to facilities to verify it is a matter of proliferation concern”.The US has claimed preventing Iran from acquiring a nuclear weapon – an ambition that Tehran continues to deny – as the motivation for the war that it launched in March. However, Tehran has been successful in shifting the focus of the hostilities to control of the strategic Strait of Hormuz waterway.In particular, the IAEA report raised concerns over the lack of access to the Isfahan plant, which was targeted several times by the US and Israel over the past year or so.In the report, IAEA Director General Rafael Grossi expressed his “conviction that the long-standing problems and recurrent crises surrounding these issues must be resolved through a long-lasting, verifiable diplomatic agreement”.However, Iran has said that access to the sites that have been struck by military action must be arranged via special arrangement.The head of Iran’s Atomic Energy Organization, Mohammad Eslami, said on August 26 that the IAEA “cannot seek to inspect these centres until it develops specific criteria and protocols for inspecting sites targeted by military attacks”.Tehran suspended cooperation with the UN nuclear watchdog following US and Israeli attacks on Iran in June 2025 that included strikes on nuclear sites before saying in September 2025 it would allow the UN agency’s inspectors to return.
