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.

Iran’s president has ordered the country to suspend its cooperation with the International Atomic Energy Agency after American airstrikes hit its most-important nuclear facilities.

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.
