The International Atomic Energy Agency (IAEA) reports that Iran continues to deny inspectors access to nuclear facilities, preventing verification of near bomb-grade uranium stockpiles. Director General Rafael M. Grossi called for immediate inspector access "with the utmost urgency," citing proliferation concerns. The 11-page report, sent to member states ahead of next week's board meeting in Vienna, details that inspectors have had no access to critical enrichment sites at Fordow, Natanz, and Isfahan since June 2025, when U.S. and Israeli bombing campaigns targeted Iranian nuclear facilities.

Based on Iranian data through June 12, Iran held an estimated 9874.9 kilograms of enriched uranium, including 184.1 kilograms at 20% enrichment and 440.9 kilograms at 60% — close to weapons-grade. However, the agency cannot confirm current stockpile size, composition, location, or whether enrichment continues. Iran also refuses access to a fourth facility near Isfahan announced in June 2025, whose exact location remains unknown.

Iran denies seeking nuclear weapons but has not explained 60% enrichment levels far exceeding civilian needs. The IAEA reports Iran has promised access to civilian plants at Bushehr later this month, though critical enrichment sites remain off-limits.
