DUBAI, United Arab Emirates—A problem with the electrical distribution grid at Iran’s Natanz nuclear facility caused an incident at the site on April 11, Iranian Press TV reported, a day after Tehran launched new advanced uranium enrichment centrifuges at the site.
The Natanz facility, which is located in the desert in the central province of Isfahan, is the centerpiece of Iran’s uranium enrichment program and monitored by inspectors of the International Atomic Energy Agency, the U.N. nuclear watchdog.
“The incident caused no casualties or contamination,” Iran’s Atomic Energy Organization spokesman Behrouz Kamalvandi said, adding that “electricity was affected at the Natanz facility.”
The cause is under investigation, Kamalvandi told Iran’s semi-official Fars news agency; Iranian lawmaker Malek Shariati-Niasar said in a tweet, “This incident ... is strongly suspected to be sabotage or infiltration.”
Iran has blamed Israel for last year’s killing of Mohsen Fakhrizadeh, who was believed by Western intelligence services to be the mastermind of a covert Iranian nuclear weapons program. Tehran has denied seeking to build a nuclear bomb. Israel has neither confirmed nor denied responsibility for the killing.
A spokesman for the U.N. nuclear watchdog said by email: “We are aware of the media reports. We have no comment at this stage.”
In July last year, a fire broke out at the Natanz facility, which the regime claimed was an attempt to sabotage Iran’s nuclear program. In 2010, the Stuxnet computer virus, widely believed to have been developed by the United States and Israel, was discovered after it was used to attack Natanz.
Tehran and Washington have been trying to revive Iran’s 2015 nuclear deal with major powers after former U.S. President Donald Trump abandoned it three years ago. Trump reimposed sanctions that had been lifted on the Islamic Republic, and brought in many more.
In reaction to the U.S. sanctions, Iran disclosed it was in breach of many restrictions imposed by the accord. The two nations laid out tough stances at indirect talks in Vienna last week on how to bring both sides back into full compliance with the accord.
