The UN’s nuclear agency, IAEA, has warned that Iran could restart making enriched uranium within a few months—even after recent US and Israeli attacks damaged its nuclear sites. IAEA chief Rafael Grossi said Iran’s nuclear program is still partly intact, and the country has the knowledge and tools to resume work quickly.

Earlier this month, Israel launched attacks on Iran’s nuclear and military facilities under “Operation Rising Lion” to stop Iran from building nuclear weapons—a claim Iran denies. The US then joined in, bombing three key nuclear sites. President Trump claimed the attacks destroyed Iran’s nuclear program completely and set them back “decades.” Iran’s foreign minister admitted the damage was serious but did not give details.

Grossi told CBS News that Iran might still have some centrifuges working and may have even moved some of its enriched uranium. Iran had over 400 kg of uranium enriched to 60%, which is close to weapons-grade. Grossi said it’s unclear where that uranium is now, and he hasn’t been allowed to visit the damaged sites.

Meanwhile, Iran has cut cooperation with the IAEA, and its lawmakers have blocked Grossi’s visit to sites like Fordo, the main enrichment plant.

President Trump also threatened to bomb Iran again if it continues uranium enrichment. He said he stopped Israel and the US from killing Iran’s Supreme Leader, Khamenei, during the strikes but criticized Khamenei’s remarks and warned that future military action is possible. Iran responded that no deal is possible unless the US stops insulting their leader.
