Iran will continue to engage with the UN’s nuclear watchdog even after it announced the suspension of cooperation, the country’s top diplomat said, boosting hopes for oversight of its contested atomic program despite Israel’s attacks.

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.

The Iranian government has suspended cooperation with the U.N.'s International Atomic Energy Agency until the security of Iran's nuclear facilities and activities is assured.
