In a report to member states, the International Atomic Energy Agency (IAEA) said that Iran had increased its stockpile of uranium enriched to 60% purity from 274.8 kilograms to 408.6 kilograms since early February. IAEA Director General Raphael Grossi said that the rate of accumulation reflected "significantly increased production" of highly enriched uranium by Iran. According to an IAEA measure, Iran possessed enough 60%-enriched material to fuel 10 nuclear weapons at the time of the report.
