International Atomic Energy Agency Director General Rafael Mariano Grossi called Israeli President Isaac Herzog on Friday following airstrikes on Iran’s Natanz nuclear facility, an Israeli presidential spokesperson told Fox News. 

Grossi told Herzog that the facility was severely damaged in the strikes, according to Israeli media reports. 

“We are currently in contact with the Iranian nuclear safety authorities to ascertain the status of relevant nuclear facilities and to assess any wider impacts on nuclear safety and security,” Grossi said in a statement. 

“Radiation levels outside the Natanz facility remained unchanged. The type of radioactive contamination present inside the facility, mainly alpha particles, can be managed with appropriate protective measures,” he added.

“This development is deeply concerning. I have repeatedly stated that nuclear facilities must never be attacked, regardless of the context or circumstances, as it could harm both people and the environment. Such attacks have serious implications for nuclear safety, security and safeguards, as well as regional and international peace and security,” Grossi continued.

“This is the largest uranium enrichment site in Iran, which has operated for years to achieve nuclear weapons capability and houses the infrastructure required for enriching uranium to military-grade levels. As part of the strikes, the underground area of the site was damaged. This area contains a multi-story enrichment hall with centrifuges, electrical rooms, and additional supporting infrastructure,” according to the IDF.

“In addition, critical infrastructure enabling the site’s continuous operation and the Iranian regime’s ongoing efforts to obtain nuclear weapons were targeted,” it said.
