A Middle Eastern intelligence official told the New York Times that Israel planted a bomb in a building where advanced centrifuges were being developed.
A fire at Iran’s main nuclear fuel enrichment site caused significant damage, setting back the country’s nuclear program by months, the government acknowledged on Sunday, after initially saying the destruction was minor.
A Middle Eastern intelligence official with knowledge of the episode told the New York Times that Israel was responsible for the attack on the Natanz nuclear complex on Thursday, using a powerful bomb. A member of the Islamic Revolutionary Guards Corps who was briefed on the matter also said an explosive was used.
Both officials spoke on condition of anonymity when discussing sensitive intelligence and operational topics.
Suspicion in Iran has focused on Israel and the United States, which have sabotaged the nuclear program in the past and have vowed to keep Iran from developing nuclear weapons. In the past, Israel and the United States have used cyberattacks to damage Iran’s nuclear program, but that has been ruled out as a cause in this case, the Revolutionary Guards member said.
