The UN nuclear watchdog has confirmed that Iran’s key nuclear facility at Natanz was targeted in a fresh attack on Saturday, even as it reported no increase in off-site radiation levels, offering limited reassurance amid escalating tensions in West Asia.In a brief statement on its official X handle, the International Atomic Energy Agency (IAEA) said it had been informed by Iran that the Natanz enrichment site had been hit, and that it is closely assessing the situation.IAEA Director-General Rafael Grossi reiterated an urgent call for military restraint, warning that continued strikes on nuclear facilities could trigger a dangerous radiological incident.The development comes amid intensifying military activity involving Iran and Israel, with nuclear infrastructure increasingly emerging as a potential flashpoint in the widening conflict.Preliminary reports indicate that while the site was struck, no radioactive leakage has been detected outside the facility, suggesting that any potential impact remains contained for now.However, experts caution that even limited damage to nuclear infrastructure carries inherent risks. The IAEA has consistently warned that attacks on such facilities could have severe consequences for human safety, the environment and regional stability, even if immediate radiation levels appear normal.The Natanz facility, central to Iran’s uranium enrichment programme, has been targeted multiple times in the past, reflecting its strategic importance in the broader geopolitical contest over Tehran’s nuclear ambitions.Grossi emphasised that the agency is actively monitoring developments and seeking further information from Iranian authorities, while maintaining contact with inspectors on the ground.The latest strike underscores growing international concern that the ongoing conflict could spill into a nuclear safety crisis, particularly if attacks continue on sensitive installations.
