Iran yesterday accused arch-foe Israel of sabotaging its key Natanz nuclear site and vowed revenge for an attack that appeared to be latest episode in a long-running covert war.
Iran's semi-official Nournews website said the person who caused an electricity outage in one of the production halls at the underground uranium enrichment plant had been identified. "Necessary measures are being taken to arrest this person," the website reported, without giving details about the person.
The incident occurred amid diplomatic efforts by Iran and the United States to revive Tehran's 2015 nuclear deal with major powers, an accord Israel fiercely opposed, after former US President Donald Trump abandoned it three years ago.
Last week, Iran and the global powers held what they described as "constructive" talks to salvage the deal, which has unravelled as Iran has breached its limits on sensitive uranium enrichment since Trump reimposed harsh sanctions on Tehran.
Iranian authorities described the incident a day earlier as an act of "nuclear terrorism".
Yesterday, Foreign Minister Mohammad Javad Zarif explicitly blamed Israel. "The Zionists want to take revenge because of our progress in the way to lift sanctions... We will not fall into their trap...We will not allow this act of sabotage to affect the nuclear talks," Zarif was quoted by state TV as saying.
"But we will take our revenge against the Zionists."
Multiple Israeli media outlets have quoted unnamed intelligence sources as saying the country's Mossad spy service carried out a successful sabotage operation at the underground Natanz complex, potentially setting back enrichment work there by months.
Iranian nuclear energy chief Ali Akbar Salehi said an emergency power system had been activated at Natanz to offset the outage.
Russia's foreign ministry said yesterday it hoped the power outage at Natanz uranium plant would not "undermine" progress on nuclear talks.
The European Union also warned against attempts to derail talks aimed at returning the US to the nuclear deal.
EU spokesman Peter Stano said the reported incident "could have been an act of sabotage" but insisted that there had been no official attribution over who was responsible.
