UN watchdog board demands urgent Iran cooperation and site access

The International Atomic Energy Agency’s Board of Governors has adopted a resolution pressing Iran to fully cooperate with inspectors, disclose information about its stockpile of uranium enriched to 60% and grant access to nuclear sites the agency says it still cannot verify.

The vote on June 10 in Vienna sharpened pressure on Tehran at a time when the IAEA says it has been unable to account for key parts of Iran’s nuclear program since the 2025 strikes on Iranian nuclear sites. AP reported the resolution passed 21-0, with 10 abstentions and one member not voting because it was in arrears.

France, the United Kingdom, Germany and the United States sponsored the measure. The resolution described the information and access it demanded as “essential and urgent” for verifying that no nuclear material had been diverted.

What the board demanded

The board’s resolution called on Iran to provide complete information on its near-weapons-grade uranium stockpile and to allow inspectors back into facilities the agency has not been able to inspect.

AP reported that the IAEA has been denied access to sites hit in the June 2025 U.S.-Israeli strikes. The agency has also said it cannot independently confirm the current size, composition or location of Iran’s enriched uranium stockpile.

A June AP report said the IAEA had said Iran holds 440.9 kilograms of uranium enriched to 60%, a level close to weapons-grade. That stockpile remains one of the central unresolved issues in the dispute.

The same June report said inspectors had only been able to inspect the Bushehr plant since February because other facilities remained inaccessible.

Why the issue is urgent

The IAEA says the missing access leaves open questions about whether Iran has continued enrichment and whether any material has been diverted.

That uncertainty matters because the agency’s safeguards work depends on being able to verify both the location and composition of nuclear material. Without that visibility, the IAEA cannot give a full accounting of Iran’s program.

The board’s resolution reflects that concern directly. By demanding both disclosure and access, it seeks to restore the agency’s ability to check the stockpile and inspect damaged or restricted sites.

How the dispute reached this point

The latest vote builds on a chronology that began with the June 2025 strikes on Iranian nuclear facilities, which reduced the agency’s access and visibility.

After those strikes, the IAEA said it struggled to re-establish inspection coverage. The June 4 AP report said inspectors could not verify Iran’s enriched-uranium stockpile or inspect key facilities after the conflict.

A separate Washington Post report from November 2025 said Iran canceled an inspection arrangement it had agreed to after an earlier IAEA resolution demanding immediate access and detailed information about its facilities.

That sequence left the agency with unresolved stockpile questions going into the June 2026 board meeting.

The players involved

The board resolution was sponsored by France, Britain, Germany and the United States. AP reported that Russia, China and Niger voted against it, while 10 countries abstained.

IAEA Director General Rafael Grossi has repeatedly pressed for restored access as the agency tries to determine whether the program can be fully accounted for under safeguards.

Iran has said its nuclear work is peaceful and has argued that security conditions justify limits on access. The IAEA says it still cannot verify the stockpile and needs urgent access to confirm that no nuclear material has been diverted.

What happens next

The immediate question is whether Iran responds formally to the resolution and whether the IAEA can regain access to the sites it has been unable to inspect.

The sponsor states and other board members could push for further diplomatic pressure if Tehran does not cooperate. The issue could also move closer to Security Council pressure if the standoff deepens.

For now, the resolution keeps the dispute in the diplomatic track, but it also underscores how much the IAEA still cannot verify after a year of restricted visibility.
