The International Atomic Energy Agency (IAEA) has confirmed that there has been no radiation leak following recent US-led airstrikes on three of Iran’s major nuclear facilities Fordow, Natanz, and Esfahan. These attacks, carried out overnight on Sunday as part of escalating US and Israeli military actions, prompted international concerns over potential nuclear fallout. However, IAEA Director General Rafael Mariano Grossi reassured that radiation levels remain stable and there is no sign of contamination outside the affected zones.

According to the IAEA’s official statement, Iranian regulatory authorities reported no spike in radiation readings. Despite the intensity of the attacks, including the use of bunker-penetrating bombs, the UN nuclear watchdog says its satellite assessments and Iranian data do not show environmental risks at this point. The agency is also seeking to mediate between the conflicting nations, calling on both Iran and the United States to return to the negotiating table.

Among the most heavily damaged sites is the Esfahan nuclear complex, already hit multiple times by Israeli forces since June 13. Grossi confirmed “extensive additional damage” and noted that some of the affected structures may have stored nuclear material. Entrances to underground tunnels were visibly impacted, though full structural assessments are ongoing.

At the Fordow uranium enrichment facility, buried deep within a mountain, direct hits were also confirmed. However, due to its fortified location, the scale of internal damage remains uncertain. Satellite imagery reviewed by Reuters and analyzed by experts showed unusual movements at Fordow just days before the strike, including a long queue of vehicles, suggesting that Iran had anticipated the attacks. A senior Iranian official told Reuters that most of the 60% enriched uranium had already been relocated.

The Natanz facility, previously targeted in earlier attacks, also sustained fresh damage. With Iran’s stockpile of over 400 kg of highly enriched uranium, the IAEA now plans to resume on-ground verification efforts as soon as the situation allows. Grossi concluded with a plea for restraint and diplomacy: “We need to try to go back to the negotiating table as soon as possible. We have been talking to Iran, we have been talking to the United States. The IAEA is ready to play its indispensable role in this process. We have to work for peace.”
