I am writing to inform you that in the early morning hours of 11 April 2021, a dangerous, reckless sabotage at the electricity distribution network of the Natanz Fuel Enrichment Plant caused a blackout and the disruption of the operations of this sensitive nuclear facility which has been under IAEA safeguards and extensive monitoring. The timely and professional containment measures adopted by the highly dedicated management and staff of the NFEP and Iranian Atomic Energy Organization averted what could have become a human and environmental catastrophe.
The deliberate targeting of a highly sensitive safeguarded nuclear facility—with the high risk of potential release of radioactive material—constitutes reckless criminal nuclear terrorism. Considering the possible indiscriminate human and environmental consequences of this international crime, those who planned, ordered, participated and carried out this cowardly act committed a grave war crime; one that must not go unpunished. Any power with knowledge of, or acquiescence in, this act must also be held accountable as an accomplice to this war crime.
