We, the undersigned, strongly condemn the sabotage in the Natanz nuclear enrichment plant in Iran on 11 April 2021, as a form of nuclear terror. This attack has been almost universally attributed to Israel, including by the Israeli media, and confirmed by US and Israeli intelligence officials. Such attacks carry a serious risk of high level radioactive leakage which could potentially endanger the lives of thousands of innocent human beings and irreparably contaminate the environment causing long-term genetic malformations and disease, with far-reaching destructive consequences into the future.
