ISLAMABAD: The International Atomic Energy Agency (IAEA) has confirmed that four key structures were damaged at Iran’s Isfahan nuclear site in an Israeli military strike, but reported no increase in radiation levels.
The IAEA, posting on X, confirmed that the uranium conversion facility and fuel plate fabrication plant were among the affected buildings. “4 critical buildings at Isfahan nuclear site were damaged in yesterday’s attack, including the Uranium Conversion Facility and the Fuel Plate Fabrication Plant,” the IAEA said in a post on X.
Based on info available to @IAEAorg, 4 critical buildings at Esfahan nuclear site were damaged in yesterday’s attack, including the Uranium Conversion Facility and the Fuel Plate Fabrication Plant.
As in Natanz, no increase in off-site radiation expected. https://t.co/ZzhQEDSzU6

“As in Natanz, no increase in off-site radiation expected,” the agency noted, reassuring that the incident has not resulted in a radioactive leak.
IAEA Director General Rafael Mariano Grossi told the United Nations Security Council that at present, the competent Iranian authorities have confirmed that the Natanz enrichment site has been affected and that there are no elevated radiation levels.
“At Natanz, the above-ground part of the Pilot Fuel Enrichment Plant, where Iran was producing uranium enriched up to 60 per cent U-235, has been destroyed,” Grossi said. He added that “the level of radioactivity outside the Natanz site has remained unchanged and at normal levels,” indicating no external radiological impact to the population or the environment.
The Director General briefed the Council following Israeli strikes that targeted multiple nuclear-related sites in Iran. “Early this morning, the International Atomic Energy Agency was informed of the military operation launched by Israel which included attacks on nuclear facilities in the Islamic Republic of Iran,” Grossi stated.
He confirmed that the strike at Natanz also destroyed the facility’s electricity infrastructure, including “the electrical sub-station, main electric power supply building, emergency power supply and back-up generators.”
Although there was no indication of a direct attack on the underground cascade hall housing additional enrichment equipment, Grossi noted that the power loss “may have damaged the centrifuges there.”
Monitoring the situation closely
The IAEA is monitoring the situation closely and remains in contact with the Iranian Nuclear Regulatory Authority. “There is radiological and chemical contamination inside the facilities in Natanz,” Grossi said, noting that the type of radiation present, mainly alpha particles, is manageable with proper safety protocols.
Israel launched a large-scale assault early Friday, deploying approximately 200 aircraft to strike Iran’s nuclear facilities and long-range missile sites. The attacks resulted in the deaths of senior Iranian military officials and nuclear scientists.
Iran launched a barrage of missiles at Israel early Saturday as part of “Operation True Promise 3,” in retaliation for Israeli airstrikes on Iranian nuclear and military facilities that resulted in the deaths of several senior Iranian generals.
