The IAEA's latest reports found that Iran increased production of highly enriched uranium since December. In the past quarter, Iran's stock of uranium enriched to 60% purity grew by 92.5 kg to reach a total of 274.8 kg, which if enriched further is enough for six nuclear weapons, according to IAEA measures. Iran is now producing between 35 and 40 kg of uranium enriched up to 60% per month, up from between 6 to 9 kg a month prior to December.
