The head of Iran’s atomic energy agency has described mysterious power outage at the country’s main uranium enrichment facility as an act of “nuclear terrorism” by opponents of a diplomatic solution to disagreement’s over Iran’s nuclear programme.

Ali Akbar Salehi did not specify who might have been behind Sunday’s alleged attack on the Ahmadi Roshan facility, near Natanz, but he was likely referring to Israel.

Iran reserved the right to take action against the perpetrators, he told state television.

The sensitive site, in the centre of the country, lost its power supply one day after it was trumpeted by the president and other senior officials as part of an annual commemoration of the nation’s atomic technology achievements.

The alleged attack also came as US Defence Secretary Lloyd Austin arrived in Israel for talks with senior officials, and any alleged operation will likely be seen in the region as US endorsement, even though Washington likely had little do with it.

Iran and the US are struggling to resurrect a 2015 nuclear deal that placed limits on Iran’s nuclear programme in exchange for relief from international sanctions. Former president Donald Trump abandoned the deal in 2018 and tightened sanctions, prompting Iran to breach limits that the nuclear pact imposed on its programme.

President Joe Biden wants to return to the deal. Americans along with Iranian diplomats and officials from other nuclear deal signatories including the United Kingdom, Germany, France, Russia and China launched talks in Vienna last week that are to resume on Wednesday.

Israeli prime minister Benjamin Netanyahu vehemently opposes the deal and has sought to lobby Washington not to resume diplomatic negotiations with Iran.

“It seems that Israel is taking matters into its own hands to show there are other ways to stop Iran’s advances besides diplomacy,” says Mark Fitzpatrick, a former US State Department nonproliferation specialist. “The Israeli leadership thinks this diplomatic gambit is a fool’s errand, and they they have other ways to stop Iran’s march to a nuclear bomb.”

On Saturday, Iran’s president and other officials had unveiled what they described as 133 new achievements in the field of nuclear physics, including centrifuges which once perfected can more efficiently and quickly purify uranium and produce fissile material that can be used to power an electricity plant or, if highly concentrated, build an atomic bomb.

During the ceremonies, state television aired a video clip of Iranian singers dressed as scientists performing a patriotic song amid what appeared to be cascades of nuclear centrifuges. But experts say Iran often exaggerates its advances for propaganda purposes.

“Iran has been making pretty steady progress in developing more and more advanced centrifuges, but how well they work and how much of a leap forward they are is uncertain,” said Mr Fitzpatrick. “The fact that Iran has been working on so many different kinds of centrifuges suggests it hasn’t yet found one with which it is satisfied.”

The alleged attack immediately raised questions about the security of Iran’s nuclear programme. A senior Iranian lawmaker said he suspected “sabotage and infiltration”, but provided no technical explanation or details. “This incident happening on the anniversary of National Nuclear Technology Day and during the process of Iran’s efforts to force the westerners to lift the sanctions is very suspicious,” Malek Shariati-Niasar, a politician who serves as spokesman for the Iranian parliament’s energy committee, wrote in a Tweet.

The 100,000 square-meter enrichment facility at Natanz, built eight meters below the surface to withstand possible airstrikes, was struck in 2010 by the infamous Stuxnet virus, a piece of malicious computer code that reportedly damaged hundreds of Iranian centrifuges and slowed Iran’s nuclear technology programme.

In 2020, a mysterious explosion hit a workshop in Natanz where centrifuges are assembled, prompting Iran to begin building another one deep within a nearby mountain.

Both the 2010 and 2020 incidents were attributed to Israeli intelligence, with possible US collaboration. Israel was also suspected of being behind the assassination last year of Iranian military scientist Mohsen Fakhrizadeh, who is regarded as the father of Iran’s nuclear programme.

The Jerusalem Post on Sunday, citing no sources, alleged the latest incident at Natanz was not an accident but a cyberattack and that “the damage is much graver than what Iran is presenting to the public.”

Mr Kamalvandi said Iranian officials were investigating the incident on Sunday, which he said appeared related to the electrical distribution network at the uranium enrichment section at Natanz.

Iran, a signatory to the Nuclear Non-Proliferation treaty, has been locked in a dispute with much of the world since the early 2000s, when western officials alleged it had a clandestine nuclear programme. Iran says its nuclear technology pursuits are for peaceful civilian purposes only. But most non-proliferation specialists and intelligence analysts assess that Iran is advancing its nuclear programme to give itself the option to pursue a bomb if it ever chooses to do so.
