Iran has told the United Nations nuclear watchdog that it is not obliged to submit to full nuclear monitoring while it remains under threat of US military attacks, Bloomberg reported on Monday, hardening Tehran's position against international inspectors at the very moment the United States and Iran are negotiating — through Qatar — over the future of that same nuclear programme.

In a 10-page report sent to the International Atomic Energy Agency (IAEA) and circulated among diplomats late last week, Iran said assaults on its nuclear facilities and the threat of renewed strikes have made normal inspections impossible, according to Bloomberg's account of the document. The report is Tehran's formal written answer to months of IAEA pressure for access to sites bombed first by Israel and then by the United States and Israel together.

What the watchdog says it still cannot verify

IAEA Director General Rafael Mariano Grossi told the UN Security Council on October 27 that his agency has identified no activity to repair or reconstruct any of the facilities damaged in the military attacks of 2025 and 2026 — naming the Fordow enrichment plant, the pilot and main enrichment plants at Natanz, facilities at the Esfahan complex and the Khondab heavy water research reactor. But he said the agency still cannot verify Iran's previously declared stockpile of 440.9 kilograms (972 pounds) of uranium enriched to up to 60 percent purity — a short technical step from weapons-grade levels of 90 percent — cannot confirm that no safeguarded nuclear material has been diverted, and has been unable to conduct normal inspections in Iran since its inspectors were withdrawn for their safety when the attacks began in June 2025.

Grossi has stated the legal position plainly: under the Nuclear Non-Proliferation Treaty, Iran is bound to declare all nuclear material and activities and allow inspectors to verify none is diverted, and those obligations, he said, "cannot be unilaterally suspended under any circumstances." The one exception to the inspection blackout is the Bushehr nuclear power plant, where IAEA inspectors are currently undertaking verification activities, including arrangements to verify spent fuel before it is moved to a new dry storage facility.

Tehran's line has been building for months

Monday's report is the written form of a position Iranian officials have stated in pieces. In August, the head of the Atomic Energy Organization of Iran, Mohammad Eslami, said the IAEA cannot demand access to inspect facilities damaged in the US-Israeli strikes unless a specific, approved protocol for inspecting sites under wartime conditions is drafted and agreed, and that Iran's interactions with the agency are governed by a law passed by Iran's parliament after the attacks. Eslami also accused the agency of failing to condemn strikes on facilities that had been registered with and regularly inspected by the IAEA.

The timing is the story. On the same Monday that Bloomberg reported Iran's hardening line on inspections, US President Donald Trump — after meeting Qatar's prime minister at the White House — repeated that Iran will never have a nuclear weapon and called that point non-negotiable, while Tehran's own nuclear proposal, sent to Washington through Qatar last week, waits for an American answer. Verification is not a technical footnote to those talks: any deal that trades sanctions relief and an end to the blockade for limits on Iran's programme will stand or fall on whether inspectors can actually enter the sites and account for the 440.9 kilograms of highly enriched uranium. Iran's 10-page report says, in effect, that the bombing has changed what it owes — and the IAEA's chief says, in effect, that it has not.

What happens next

Diplomats who received the report must now decide whether Iran's argument changes the IAEA board's course; in September the board formally reported Iran to the UN Security Council for breaching its non-proliferation obligations, the first such referral in 20 years. Whether monitoring language enters the US-Iran framework being carried by Qatar — Tehran's two-day proposal covers the Strait of Hormuz, the blockade and bombing, with nuclear talks to follow — is the next verified test of whether this hardening is a negotiating position or a fixed line.
