The International Atomic Energy Agency (IAEA) has identified missing Iranian uranium as a proliferation concern, with its latest report showing estimates of Iran's enriched uranium stocks up to June 13, 2025 unchanged from previous reports.

IAEA assessment on Iran's uranium stocks

The IAEA's report covers Iran's enriched uranium holdings assessed up to June 13, 2025. According to the agency, its estimates of these stocks remain consistent with figures presented in earlier reports, with no revision to previously disclosed quantities.

The agency has separately flagged the issue of missing Iranian uranium as a proliferation concern, underscoring the significance it attaches to accounting for all nuclear material under its monitoring mandate.

Key findings from the IAEA report

The IAEA's dual finding, that stock estimates remain static while an accounting gap persists, reflects the agency's ongoing scrutiny of Iran's nuclear material declarations. The proliferation concern designation signals that the unaccounted uranium carries implications beyond routine monitoring discrepancies.

IAEA Director General Grossi has stated that UAE authorities responded very swiftly to the attack on the Barakah Nuclear Power Plant, which resulted in the shutdown of a reactor due to loss of external power. Grossi further noted that whoever was behind the attack knew precisely what they were doing, underscoring the calculated and targeted nature of the incident.

IAEA's Assessment of the Barakah Attack

Grossi's remarks highlight the severity and precision of the attack on the Barakah Nuclear Power Plant. The shutdown of a reactor following the loss of external power points to a deliberate disruption of critical nuclear infrastructure. The IAEA chief's observation that the perpetrators acted with precise knowledge reflects concerns about the sophistication of the threat.

IAEA's Position on Iran Deal Verification

Separately, Grossi has declared that any deal aimed at ending the Iran war cannot be conceived without robust verification and monitoring of its terms. The IAEA's position underscores the critical role international oversight bodies play in validating the terms of geopolitical agreements. Grossi emphasized that verification and monitoring are not optional components but fundamental prerequisites for any credible resolution.

IAEA Support to UAE - Abu Dhabi

Grossi also confirmed that the IAEA is extending both moral and technical support to UAE - Abu Dhabi. This dual form of engagement highlights the agency's active involvement in the region, encompassing advisory as well as operational assistance. The IAEA's commitment reflects its broader mandate to support member states with technical expertise and institutional backing.
