Summary
A recent report by the International Atomic Energy Agency (IAEA) revealed that Iran increased its stockpile of highly enriched uranium before the June 13, 2025, attacks by Israel and the United States. At the time, Iran possessed 440.9 kilograms of uranium enriched to 60%, nearing weapons-grade levels. This marked a 32.3-kilogram increase from the previous month. The report highlights that 42 kilograms of uranium enriched to 60% could theoretically be further refined to produce one nuclear bomb. Since the attacks, IAEA inspections of Iran’s nuclear facilities have ceased, leaving the current stockpile of enriched uranium unverified.
