Israel supplied Iran with centrifuge platforms containing explosives for its nuclear enrichment program, a top Iranian official has acknowledged for the first time, underscoring the sophistication of sabotage programs targeting the Islamic Republic.

The comments by Mohammad Javad Zarif, a former foreign minister who serves as vice president for strategic affairs for reformist President Masoud Pezeshkian, appear aimed at explaining to the country's disaffected public the challenges Iran's government faces under crushing Western sanctions over the program. The comments also acknowledged details previously reported in Israel about a 2021 attack on Iran's underground Natanz nuclear enrichment facility.
