IAEA Warns of Nuclear Risk from Iran Strikes
The International Atomic Energy Agency (IAEA) is warning it “cannot rule out” a possible radiological release from the ongoing military strikes in Iran. While the agency reports no current evidence of direct attacks on nuclear facilities, the statement adds a layer of nuclear anxiety to the widening conflict as the IAEA seeks access to key sites.
The IAEA has now confirmed satellite imagery shows recent damage to entrance buildings at Iran's Natanz Fuel Enrichment Plant. While the agency stated the core underground facilities were not impacted and no radiological release is expected, the confirmation reverses earlier statements that the site was untouched. Natanz is a key part of Iran's nuclear program, housing thousands of centrifuges for enriching uranium. Iran's nuclear infrastructure is spread across several key sites with varying levels of fortification. The Fordow facility is built deep inside a mountain to protect it from airstrikes, while the Bushehr plant is the country's only operating nuclear power reactor, fueled by Russia. Another major facility is near Arak, designed as a heavy-water reactor capable of producing plutonium. International anxiety is heightened by Iran's significant advancements in uranium enrichment since the collapse of the 2015 nuclear deal. According to the latest available IAEA reports, Iran's stockpile of enriched uranium is more than 30 times the limit set by the accord, with a significant quantity enriched to 60% purity — a short technical step from the 90% needed for a nuclear weapon. The diplomatic framework intended to prevent this scenario, the Joint Comprehensive Plan of Action (JCPOA), effectively ended in October 2025 when Iran announced it was no longer bound by the agreement. This followed the unilateral U.S. withdrawal in 2018 and the subsequent reimposition of sanctions, after which Tehran began progressively violating the deal's restrictions. While direct military strikes on active nuclear power plants are unprecedented, research reactors and facilities under construction have been targeted before. Iraq attacked Iran's partially-built Bushehr plant in the 1980s, and Israel famously bombed Iraq's Osirak reactor in 1981. Experts warn that a successful strike on an operating reactor or a spent fuel pool could trigger a major radiological disaster comparable to Chernobyl or Fukushima. The IAEA's ability to monitor the situation is severely hampered. Director General Rafael Grossi noted that communication with Iranian nuclear authorities has been sporadic since the strikes. Furthermore, Iran suspended IAEA access to facilities affected by earlier strikes in 2025, creating critical gaps in the agency's knowledge of Iran's nuclear material and activities.
