Israel and the U.S. struck Iranian nuclear facilities, resulting in what Trump has described as "total obliteration" of three sites: Fordow, Natanz, and Isfahan. Israel said Iran had nuclear ambitions that posed an existential threat to its existence.

The decision means that international inspectors will not be able to oversee sites. Experts have warned that Tehran could revive plans to build a bomb.

Iranian President Masoud Pezeshkian has approved a law to halt cooperation with the International Atomic Energy Agency (IAEA), a move which will likely obscure any attempt by Tehran to restart its damaged nuclear program.
