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.

Israel's campaign against Iran's nuclear program has significantly impacted Natanz, incapacitating centrifuges and potentially causing an underground implosion, an Israeli official tells The Wall Street Journal.

The IAEA has said that "no increase in off-site radiation" has been recorded at either Natanz or Esfahan.

IAEA inspectors will continue to remain in Iran and will resume on-site inspections “as soon as safety conditions permit,” he stated.

Columns of smoke rose Friday over Iran’s main nuclear enrichment facility at Natanz after Israeli strikes on the country.

The International Atomic Energy Agency's Rafael Grossi said there was no further damage to Iran's Natanz enrichment site as the Fordow site, which is underground, remains untouched by Israel's attacks.

The Israeli military said it inflicted "significant damage" on Iran's Natanz enrichment site. The IDF said in a statement Friday afternoon that it had hit the underground complex at Natanz, which includes a multilevel enrichment hall containing centrifuges,

Natanz, Isfahan and Fordow, killing several Iranian nuclear scientists. The facilities are heavily fortified and largely underground, and there are conflicting reports of how much damage has been done.
