Iran's nuclear enrichment advances as it stonewalls UN, IAEA reports show

Iran has enough uranium enriched to up to 60% purity, close to weapons-grade, for three atom bombs by the International Atomic Energy Agency's definition and is still stonewalling the agency on key issues, confidential IAEA reports showed on Wednesday.

Iran's stock of uranium enriched to up to 60% grew by 6.7 kg to 128.3 kg since the last report on Sept. 4, one of the two reports to member states seen by Reuters said. That is more than three times the roughly 42 kg that by the IAEA's definition is theoretically enough, if enriched further, for a nuclear bomb.

Weapons-grade is around 90% purity.
