UN nuclear watchdog voices growing concern over Iranian enrichment plant it cannot inspect
Iran tells the agency talks on inspections cannot resume under US threats, while the IAEA says it does not know the plant's exact location.

The International Atomic Energy Agency, the UN nuclear watchdog, said in a confidential report to member states, circulated on Friday, Nov. 13, that it is "increasingly concerned" Iran has not let it inspect the Isfahan Fuel Enrichment Plant. Iran declared the underground plant on June 12, 2025.
An inspection planned for the next day was cancelled when the bombing of Iranian nuclear sites began. The agency says it does not know the plant's exact location, its status or whether it holds nuclear material. It calls the lack of information on Iran's nuclear material a matter of serious proliferation concern that needs to be fixed with "utmost urgency."
Iran has not let inspectors return to any bombed sites, and the agency has been unable to verify the stockpile of near weapons-grade uranium. The report says Iran told the agency that talks on resuming inspections cannot continue amid public threats by the US president of further armed aggression. Iran also reaffirmed its commitment to resume full safeguards once conditions permit.
The IAEA says it is ready to resume its work at short notice and encourages Iran to consider technical and gradual measures. Al Jazeera adds that the report did not establish that enrichment is taking place at the plant.

Iran's refusal of access, within the war
CBS News folds the report into its Iran war roundup, opening with the IAEA being "increasingly concerned" about access to the underground Isfahan plant, where, according to Reuters, highly enriched uranium is thought to be buried. It sets that beside President Trump's remark "We don't need a deal with Iran" and Iran's claim that US officials asked Putin to facilitate talks. Al Jazeera English headlines the agency's call for Iran to reopen its facilities to inspection, notes the report did not establish that enrichment is taking place at Isfahan, and relays Foreign Ministry spokesperson Esmaeil Baghaei's blame of US and Israeli attacks for limiting cooperation.
HuffPost runs the Reuters report, which notes that the bombing rendered the June 13, 2025 inspection impossible and that Grossi, speaking in March, said the IAEA reckoned a significant quantity of Iran's most highly enriched uranium sat in the Isfahan tunnel complex. The Boston Globe carries the AP wire report, which opens with Iran telling the IAEA that monitoring talks cannot proceed under threat.

Watchdog's concern, with background on Iran's stockpile
BBC News headlines the agency being "increasingly concerned" about a site it has not been allowed to inspect, then adds background. Under the 2015 deal Iran agreed to cap its stockpile at 300kg and enrichment at 3.67%, and it later exceeded both. Before the June 2025 strikes it had an estimated 441kg enriched to 60%.
The condition of Isfahan's underground facilities, BBC says, is not clear. It also notes that the US and Israel said they struck to stop Iran developing nuclear weapons, which Iran denies seeking. Courthouse News runs the AP wire report, which leads with Iran telling the agency that talks cannot resume amid what it calls "persistent, explicit, and public threats" by the US president.
It also reports Iran's "firm commitment" to resume safeguards when conditions permit, the IAEA's urging of "technical and gradual measures," and Iran's concern over a US reward offer of up to $20 million.

Iran refusing inspectors at a site Trump bombed
Breitbart News frames the story as "multiple news reports" on a confidential IAEA document, and says the Isfahan plant was reportedly among the sites Trump approved strikes against in June 2025. It cites the Times of Israel on the agency telling members it cannot conclude there has been no diversion of declared nuclear material. It quotes Grossi's March estimate of "a bit more than 200 kg" of 60% uranium at Isfahan.
It also quotes Foreign Ministry spokesman Esmaeil Baqaei saying the agency has no mechanism or protocol for inspecting damaged facilities under current circumstances and that surrendering enriched uranium to be taken out of the country is "off the table." Breitbart describes Iranian officials as having "aggressively" refused to negotiate on the nuclear issue, and notes that Grossi is running to replace UN Secretary-General Antonio Guterres. The Washington Times headlines "Iran won't allow inspectors at uranium bunker" and reports that the agency said Friday it is "increasingly concerned," placing the Isfahan plant 270 miles south of Tehran.
