Iran says 2 UN watchdog devices at nuclear site turned off

TEHRAN, Iran -- Iran turned off two surveillance devices Wednesday used by U.N. inspectors to monitor the Islamic Republic's uranium enrichment, further escalating the crisis over its atomic program as Tehran's nuclear deal with world powers remains in tatters.

The move appeared to be a new pressure technique just before the International Atomic Energy Agency's board of governors, meeting in Vienna, approved a resolution to criticize Iran put forward by Western nations. The censure deals with what the watchdog refers to as Iran's failure to provide "credible information" over nuclear material found at undeclared sites across the country.

But Iran's latest move, announced by state television, makes it even more difficult for inspectors to monitor Tehran's nuclear program. Nonproliferation experts have warned Iran now has enough uranium enriched close to weapons-grade levels to pursue an atomic bomb if it chooses to do so.

The state TV report, later repeated by other Iranian media, said authorities deactivated the "beyond-safeguards cameras of the measuring Online Enrichment Monitor ... and flowmeter." That apparently refers to the IAEA's online monitors that watch the enrichment of uranium gas through piping at enrichment facilities.

In 2016, the IAEA said it installed the device for the first time in Iran's underground Natanz nuclear facility, its main enrichment site, located some 125 miles south of the capital, Tehran. The device allowed for "around-the-clock monitoring" of the facility's cascades, a series of centrifuges hooked together to rapidly spin uranium gas to enrich it.

"Traditional methods of sampling and analysis can take three weeks or longer, mostly because of the time it takes to ship the sample from Iran to the IAEA's laboratories in Austria," the agency said at the time.

Iran is also enriching uranium at its underground Fordo facility, though the IAEA is not known to have installed these devices there.

"The Islamic Republic of Iran has so far had extensive cooperation with the International Atomic Energy Agency," state TV said in its report Wednesday. "Unfortunately, the agency, without considering this cooperation ... not only did not appreciate this cooperation, but also considered it a duty of Iran."

Tehran said its civilian nuclear arm, the Atomic Energy Organization of Iran, monitored the shutdown of the cameras. It said 80% of the existing cameras are IAEA "safeguard" cameras and they will continue to operate as before. Safeguards refer to the IAEA's inspections and monitoring of a country's nuclear program.

The Vienna-based IAEA declined to immediately comment. However, Iran's move come after IAEA Director-General Rafael Mariano Grossi criticized Iran for failing to provide "credible information" about unexplained nuclear material discovered at three undeclared Iranian sites -- long a point of contention between the agency and Tehran.

U.S. Ambassador Laura S.H. Holgate identified the Iranian sites in comments Wednesday to the IAEA's board as Marivan, Turquzabad and Varamin. Iran has denied carrying out nuclear work at these locations.

Iran already has been holding footage from IAEA surveillance cameras since February 2021 as a pressure tactic to restore the atomic accord.

Iran and world powers agreed in 2015 to the nuclear deal, which saw Tehran drastically limit its enrichment of uranium in exchange for the lifting of economic sanctions. In 2018, then-President Donald Trump unilaterally withdrew America from the accord, raising tensions across the wider Middle East and sparking a series of attacks and incidents.

Talks in Vienna over Iran's tattered nuclear deal have been stalled since April. Since the deal's collapse, Iran runs advanced centrifuges and has a rapidly growing stockpile of enriched uranium. Nonproliferation experts warn Iran has enriched enough up to 60% purity -- a short technical step from weapons-grade levels of 90% -- to make one nuclear weapon should it decide to do so.

Iran insists its program is for peaceful purposes, though U.N. experts and Western intelligence agencies say Iran had an organized military nuclear program through 2003.

Building a nuclear bomb would still take Iran more time if it pursued a weapon, analysts say, though they warn Tehran's advances make the program more dangerous. Israel has threatened in the past that it would carry out a preemptive strike to stop Iran -- and already is suspected in a series of recent killings targeting Iranian officials.

Russian President Vladimir Putin called Iranian President Ebrahim Raisi on Wednesday and discussed the need to revive the nuclear deal, the Kremlin said.

The censure resolution at the IAEA meeting in Vienna, sponsored by Germany, France, the U.K. and U.S., passed with the support of 30 of 35 governors. Russia and China voted against, Russian ambassador Mikhail Ulyanov wrote on Twitter. India, Libya and Pakistan abstained.

After the vote, a joint statement from France, Germany, and the U.K. and the U.S. said the censure "sends an unambiguous message to Iran that it must meet its safeguards obligations and provide technically credible clarifications on outstanding safeguards issues."

Iran's Foreign Ministry meanwhile criticized the censure as a "political, incorrect and unconstructive action."

An Iranian official earlier warned IAEA officials that Tehran was now considering taking "other measures" as well.

"We hope that they come to their senses and respond to Iran's cooperation with cooperation," said Behrouz Kamalvandi, a spokesman for the Atomic Energy Organization of Iran. "It is not acceptable that they show inappropriate behavior while Iran continues to cooperate."

Wednesday night, a drone exploded in the northern Iraqi city of Irbil in its Kurdish region, slightly wounding three people and damaging cars and a nearby restaurant, officials said. While no one immediately claimed the attack, Iran has targeted Irbil in the past amid the regional tensions.
