Iranian Vice President Mohammad Javad Zarif claimed in a recent interview that Israel had planted explosives in equipment purchased for Tehran’s nuclear program.

According to a translation of the interview published by Iran International on Wednesday, “Our colleagues had purchased a centrifuge platform for the Atomic Energy Organization, and it was discovered that explosives had been embedded inside it, which they managed to detect.”

The timeline of the alleged incident remains unclear, according to the outlet, which is associated with the Iranian opposition. The revelation follows a series of security incidents involving Iran’s nuclear facilities, including a power failure at the Natanz uranium enrichment site in April 2021.
