A confidential report from the International Atomic Energy Agency (IAEA), circulated among member states, indicates that Iran has stored and developed uranium enriched to near-weapons grade levels (60% — just below the roughly 90% typically considered weapons grade), raising serious concerns about potential nuclear weapons capability.

The IAEA emphasized that it does not have full access to key facilities following recent conflict-related damage and therefore cannot fully verify the scale or intent of Iran’s enrichment activities. As a result, determining whether Iran previously researched or worked on nuclear warhead design remains complex and highly controversial.
