UN watchdog presses Iran for access to Isfahan site as MPs debate NPT exit

The UN nuclear watchdog says it is "increasingly concerned" about an Isfahan enrichment plant it has not been able to inspect, while Iranian MPs debate leaving the Non-Proliferation Treaty. The reports do not say whether the plant has been built.

What happened

The International Atomic Energy Agency (IAEA), the United Nations nuclear watchdog, says it is "increasingly concerned" about a uranium-enrichment plant in Isfahan that Iran declared to it last year but has still not allowed inspectors to visit. The concern appears in a confidential IAEA report on Iran, reported on 13 November 2026 and seen by Reuters and the Associated Press, according to CBC News.

The report refers to the plant as IFEP. It says: "The agency does not know IFEP's exact location, status for safeguards purposes or whether it contains nuclear material." It adds that the agency is also increasingly concerned that Iran has not allowed it to inspect the plant or see design plans.

The BBC News reported the same report and quoted it as calling the lack of information "a matter of serious proliferation concern" that "needs to be rectified with the utmost urgency". The Hindu quoted the same phrase about urgency.

Why it matters

According to The Hindu, the report says the agency is not able to conclude that there has been no diversion of declared nuclear material from peaceful nuclear activities in Iran. The report links this to the lack of cooperation from Iran and describes it as a serious proliferation concern.

CBC News reports, citing the IAEA, that Iran maintains a stockpile of 440.9 kilograms of uranium enriched up to 60 per cent purity. CBC describes this as a short, technical step away from weapons-grade levels of 90 per cent. The sources do not say when the stockpile was measured.

Background

Israel and the United States struck Iran's nuclear sites in a 12-day campaign in June 2025, according to CBC News. The strikes destroyed or badly damaged Iran's other uranium-enrichment plants, which CBC describes as the heart of its nuclear programme. Iran has not let IAEA inspectors return to any of the bombed facilities.

According to CBC News, the only facility the IAEA has inspected in Iran since June 2025 is the Bushehr nuclear power plant. Inspectors visited it from 12 to 15 September. The sources cited do not give the year of that visit.

The BBC reports that Iran told the IAEA of plans to set up the Isfahan plant a day before Israel began attacking its nuclear sites in June 2025, and that Iran initially agreed to let inspectors visit the facility. According to the BBC, that visit was cancelled after the attacks began the following day. No other saved source confirms this account.

The IAEA's director general has encouraged Iran to consider "technical and gradual measures" that would allow inspectors to return, according to The Hindu. Iran's position, as stated in the report, is that the situation will not be resolved until "the root causes of the present situation are addressed and the essential requirements for normal safeguards implementation are restored", according to CBC News.

What each side says

The IAEA says it lacks information about Iran's nuclear material and about access to facilities to verify it. It has called this a serious proliferation concern.

Iran says its nuclear programme is for peaceful civilian purposes only, according to BBC News. The Hindu reports that on Wednesday, 11 November, Iran criticised a reward announced by the US military the previous week and urged the IAEA and the UN Security Council to condemn it. The sources do not explain the reward.

The United States and Israel say their strikes aimed to prevent Iran developing nuclear weapons. Iran has consistently denied seeking them, according to BBC News.

In parliament, Euronews reports that Iranian MPs are debating nuclear doctrine and a possible withdrawal from the NPT. Ghazanfari, quoted by Euronews, said that Iran cannot be indifferent to nuclear threats from the United States and Israel, which he said target the people of Iran and the country's existence. He said that reviewing the defence doctrine and building deterrence had become a public and national demand. He also said that a withdrawal plan had been blocked by some members of parliament's presiding board last year and that obstruction efforts still prevent it from reaching the floor.

Euronews also quotes a passage arguing that nuclear deterrence requires more than an atomic bomb. The saved text does not clearly name the speaker of this remark, so it should not be attributed to Ghazanfari. The Foreign Ministry, according to Euronews, has said Iran remains committed to the Treaty on the Non-Proliferation of Nuclear Weapons.

What is still unknown

  • Whether the Isfahan plant exists in operating form. CBC News describes a plant that Iran declared, while the BBC says Iran informed the IAEA of plans to set one up. Neither report says whether the plant has been built.
  • Whether the plant holds nuclear material, and where it is.
  • Whether Iran will allow IAEA inspectors to return to the plant or to the bombed facilities.
  • Whether parliament will bring the NPT withdrawal plan to a vote.
  • Whether Iran's defence or nuclear doctrine will change. Euronews reports debate, not a decision.
  • What the US military reward referred to by The Hindu involves. No other saved source explains it.

What to watch next

Watch for any response from Iran to the IAEA's request for access, and whether the agency reports further progress on the Isfahan plant. Also watch whether Iran's parliament moves the NPT withdrawal plan onto the floor, and how the Foreign Ministry's stated commitment to the treaty fits with that debate.

Analysis: the IAEA report comes from the UN agency, while the parliamentary debate takes place inside Iran. The two are separate tracks. The agency says it cannot verify the status of nuclear material, while MPs argue that building deterrence has become a national necessity. The sources do not show whether the two are linked in policy.
