UN Security Council says IAEA has lost full oversight of Iran's nuclear program

The UN Security Council met under the “non‑proliferation” agenda to review the implementation of Resolution 2231 (2015), which endorsed the JCPOA. Representatives of Bahrain and the five European Council members (Denmark, France, Greece, Latvia and the United Kingdom) attended, while Russia and China argued that the resolution expired in October 2025. The majority of members warned that sanctions on Iran remain in force and that the International Atomic Energy Agency has lost the ability to fully monitor Iran’s nuclear facilities after the U.S.–Israel strikes of February 2026, raising serious proliferation concerns.

Council members urged Iran to restore on‑site inspections, curb escalation and fully comply with its obligations, warning that failure would increase regional pressure and instability. Greece reiterated its commitment to the global non‑proliferation architecture. The United States’ deputy ambassador, Tammy Brooks, said the diplomatic door stays open but Tehran will be held accountable for any violations, adding that attacks on non‑military targets would prompt a response. French envoy Zerom Bonafon described the U.S.–Iran memorandum as a “first positive step” toward halting hostilities, reopening the Strait of Hormuz and negotiating a non‑proliferation agreement within 60 days as a precondition for lifting sanctions. UN Deputy Secretary‑General Rosmary Di Carlo presented a report dated 19 June 2026 confirming that the IAEA has performed no on‑site verification in Iran since the strikes. Germany signalled readiness to support sanction relief after verifiable compliance. Iran’s ambassador rejected the council session as illegal, maintaining that its nuclear program is peaceful.
