Iran began enriching uranium up to 60% purity Friday, its highest level ever, after an attack targeted its Natanz nuclear site, the country’s parliament speaker said.
The comment by Mohammad Bagher Qalibaf, quoted by state television, did not elaborate on the amount Iran planned to enrich. However, it is likely to raise tensions even as Iran negotiates with world powers in Vienna over a way to allow the U.S. back into the agreement and lift the crushing economic sanctions it faces.
The announcement also marks a significant escalation after the sabotage that damaged centrifuges, an attack this past weekend suspected of having been carried out by Israel. While Israel has yet to claim it, the country is widely suspected of having carried out the still-unexplained sabotage at Natanz, Iran’s main enrichment site.
“The will of the Iranian nation is a miracle-maker and it will defuse any conspiracy,” state television quoted Qalibaf as saying. He said the enrichment began just after midnight Friday.
The head of the Atomic Energy Organization of Iran, the country’s civilian nuclear arm, later acknowledged the move to 60%, according to state TV. Ali Akbar Salehi said more details would be forthcoming and declined to further elaborate.
It wasn’t clear why the first announcement came from Qalibaf, a hard-line former leader in the paramilitary Revolutionary Guard already named as a potential presidential candidate in Iran’s upcoming June election.
While 60% is higher than any level Iran previously enriched uranium, it is still lower than weapons-grade levels of 90%.
Iran had been enriching up to 20% — even that was a short technical step to weapons grade. The deal limited Iran’s enrichment to 3.67%.
The International Atomic Energy Agency, which monitors Iran’s nuclear program, did not immediately respond to a request for comment. Earlier this week, it sent its inspectors to Natanz and confirmed Iran was preparing to begin 60% enrichment at an above-ground facility at the site.
The heightened enrichment could inspire a further response from Israel amid a long-running shadow war between the nations.
Israeli Prime Minister Benjamin Netanyahu has vowed never to allow Tehran to obtain a nuclear weapon and his country has twice preemptively bombed Mideast nations to stop their atomic programs.
Iran insists its nuclear program is peaceful, though the West and the IAEA say Tehran had an organized military nuclear program up until the end of 2003. An annual U.S. intelligence report released Tuesday maintained the American assessment that “Iran is not currently undertaking the key nuclear weapons-development activities that we judge would be necessary to produce a nuclear device.”
Iran previously had said it could use uranium enriched up to 60% for nuclear-powered ships. However, the Islamic Republic currently has no such ships in its navy.
The threat of higher enrichment by Iran already had drawn criticism from the U.S. and three European nations in the deal — France, Germany and the United Kingdom.
The 2015 nuclear deal, which former President Donald Trump unilaterally withdrew the U.S. from in 2018, prevented Iran from stockpiling enough high-enriched uranium to be able to pursue a nuclear weapon if it chose in exchange for the lifting of economic sanctions.
The weekend attack at Natanz was initially described only as a blackout in the electrical grid feeding above-ground workshops and underground enrichment halls — but later Iranian officials began calling it an attack.
Alireza Zakani, the hard-line head of the Iranian parliament’s research center, referred to “several thousand centrifuges damaged and destroyed” in a state TV interview. However, no other official has offered that figure and no images of the aftermath have been released.
Satellite images from Planet Labs Inc. obtained by The Associated Press show no apparent above-ground damage at the facility.
