An Israeli military strike on Iran's nuclear complex at Natanz directly hit the underground uranium enrichment plant there, the U.N. nuclear watchdog said on Tuesday, revising its assessment after initially reporting it had been hit only indirectly.

The head of the International Atomic Energy Agency says there is a possibility of both radiological and chemical contamination within Iran’s main nuclear enrichment facility in Natanz.

The IAEA has updated its assessment of Israeli airstrikes on Iran's Natanz facility, confirming that the strikes had direct impacts on the underground centrifuge halls.
