IAEA warns of restricted access in Iran as Western states seek UN Security Council referral

The UN nuclear watchdog has urged Iran to cooperate fully with inspections, saying limits on its access undermine verification efforts, while several Western countries are pressing to send Iran's nuclear dossier to the United Nations Security Council.

The International Atomic Energy Agency (IAEA) has issued a warning about constraints on its ability to inspect parts of Iran's nuclear programme and has called on Tehran to provide fuller cooperation to enable adequate verification. The agency said restricted access is impeding its monitoring work, increasing uncertainty about nuclear activities in the country.

The warning comes as a group of Western states are pushing to refer Iran's nuclear file to the UN Security Council. Those governments argue that the IAEA's concerns warrant escalation to the Security Council for further scrutiny and potential diplomatic action.

A Security Council referral would move Iran's nuclear dossier from the IAEA's supervisory framework into the arena of broader international diplomacy and political debate. Western officials pushing the referral say it is necessary to address outstanding questions about Iran's compliance with its safeguards obligations, while other countries have cautioned against steps that could heighten tensions.

The developments underscore the diplomatic strains surrounding Iran's nuclear programme. The IAEA's call for cooperation highlights the central role of transparency and access in the agency's work, and the push for referral to the Security Council reflects differing international views on how best to respond to unresolved nuclear verification issues.

Observers say how Tehran responds to the IAEA's requests and how UN member states handle the proposed referral will influence diplomatic dynamics and the prospects for technical verification going forward. The IAEA has emphasized that uninterrupted access is essential for it to fulfil its statutory mandate of monitoring nuclear programmes and assuring the international community of their peaceful nature.
