Iran has two known underground nuclear enrichment sites, the one Israel attacked on the first day of its assault at Natanz, and another at Fordo. Both sit south of Tehran in central Iran, but Fordo has long been the Iranian nuclear facility of most concern to international monitors and experts.

International nuclear energy watchdog says there have been no reports of increased off-site radiation levels following the US strikes on the Iranian sites. Israeli Prime Minister Benjamin Netanyahu praises Trump’s “bold decision” and says Israel and the US acted in “full coordination”.

"We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan," President Donald Trump said Saturday. Trump's decision to join Israel's campaign against Iran sharply escalates the conflict.
