The United Nations has raised fresh concerns over Iran’s nuclear programme after revealing that international inspectors no longer have a clear picture of what is happening inside the country’s nuclear facilities. The warning came after recent US and Israeli strikes on Iranian nuclear sites, which reportedly disrupted monitoring activities by the International Atomic Energy Agency (IAEA). The development has sparked fresh global concern as diplomats fear growing uncertainty over Iran’s nuclear activities could increase tensions across the Middle East.
IAEA loses access to Iran’s nuclear programme
The warning was delivered during a meeting of the United Nations Security Council by Rosemary DiCarlo, the UN’s Under-Secretary-General for Political and Peacebuilding Affairs. Referring to the latest report on UN Security Council Resolution 2231, she said the IAEA has suffered a major loss of visibility into Iran’s nuclear programme following the recent military attacks.

According to the IAEA, inspectors have not been able to carry out field verification under the Nuclear Non-Proliferation Treaty (NPT) safeguards agreement after the strikes. These inspections are considered essential for confirming that nuclear materials are being used only for peaceful purposes.
The agency also believes that facilities involved in uranium ore processing, centrifuge production and heavy water activities may have suffered damage during the attacks.
No inspections since attacks raise fresh concerns
UN officials said the IAEA has not received updated information from Iran regarding its nuclear programme and has also been unable to access nuclear sites since the attacks. Without physical inspections, the agency cannot independently verify the current status of Iran’s nuclear facilities or ongoing activities.
The lack of access has increased uncertainty over Iran’s nuclear programme, with experts warning that limited monitoring makes it harder for the international community to assess developments accurately. The situation has become a major topic of discussion at the UN Security Council amid growing concerns over regional security.
Satellite images fuel new questions
Fresh satellite images have added to the concerns surrounding Iran’s nuclear programme. According to reports cited by CNN, new construction activity has reportedly been observed at the Taleghan-2 nuclear weapons research facility inside the Parchin military complex, located southeast of Tehran.
The reported rebuilding work has raised questions about whether Iran is restoring damaged nuclear infrastructure despite earlier understandings aimed at maintaining the status quo after recent military tensions. While Iranian authorities have not officially commented on the reports, the images have attracted close attention from international observers.
UN urges diplomacy despite rising tensions
Despite growing uncertainty, UN officials stressed that diplomacy remains the only viable path forward. Rosemary DiCarlo urged all parties to engage in constructive negotiations and work toward a peaceful, comprehensive and lasting solution to the Iranian nuclear issue.
She said any future agreement should remain consistent with the objectives of UN Security Council Resolution 2231 while strengthening international peace and security. The UN believes that restoring dialogue and allowing international inspectors to resume monitoring activities will be essential to rebuilding confidence and reducing the risk of further conflict.
As questions continue over Iran’s nuclear programme, the inability of the IAEA to verify activities on the ground has become one of the biggest concerns facing the international community. Until inspections resume, uncertainty is expected to remain high, keeping the Middle East and global powers on alert.
