An incident at Iran's Natanz nuclear facility on Sunday was caused by an act of "nuclear terrorism", the country's nuclear chief Ali Akbar Salehi said, according to state TV.
Earlier on Sunday, the spokesman for the country's Atomic Energy Organization (AEOI) had said that a problem with the electrical distribution grid of the Natanz site had caused an incident, Iranian media reported.
"While condemning this despicable move, Iran emphasizes the need for the international community and the International Atomic Energy Agency to deal with this nuclear terrorism and reserves the right to take action against the perpetrators," Salehi said. He did not elaborate.
Asked about the incident, an IAEA spokesman said by email, "We are aware of the media reports. We have no comment at this stage."
