IAEA reports Iran held about 441 kg of 60% enriched uranium on eve of the strikes

In its September verification and monitoring report, the IAEA calculated that on the eve of the June 2025 attacks Iran possessed 440.9 kg of uranium enriched up to 60% U-235, close to weapons grade. The agency said it had had no access to safeguarded facilities except the Bushehr power plant since mid-June and could not verify the current location or condition of the stockpile, warning it needed Iran's full cooperation to inspect the 'massively damaged' sites.
