• Iran refuses IAEA access to Fordow, Natanz, and Isfahan facilities damaged in June 2025 strikes, citing lack of inspection guidelines for attacked sites.
  • The move complicates JCPOA revival efforts and escalates geopolitical tensions, with Iran dismissing political pressure from the U.S., European nations, and Israel.
  • IAEA Director General Rafael Grossi emphasizes the need for full access to verify nuclear material, while Iran highlights its historical cooperation and the expiration of UN Security Council Resolution 2231.

Iran's Vice President and head of the Atomic Energy Organization, Mohammad Eslami, stated on December 24, 2025, that Tehran is rejecting International Atomic Energy Agency (IAEA) inspections of nuclear sites at Fordow, Natanz, and Isfahan, which were bombed by U.S. and Israeli strikes in June 2025. According to people familiar with the matter, Iran is demanding that the agency first establish specific protocols for inspecting such damaged facilities, arguing that no existing guidelines cover this unprecedented scenario. Eslami emphasized that political pressure from the U.S., three European nations, and Israel is ineffective until clear rules are set, dismissing claims of non-compliance as baseless.

IAEA Director General Rafael Grossi confirmed that inspectors currently have access to undamaged sites but face restrictions at the three key facilities containing nuclear material. In a recent briefing, Grossi called full access essential for verification, stating, "Without comprehensive inspections, we cannot ensure the integrity of safeguards." This standoff comes amid intense economic strain in Iran, with social dissent and post-war recalibration exacerbating sanctions and instability, though no direct market trends are immediately tied to this rejection. Analysts note that the move risks stalling JCPOA revival talks, which have been in a precarious state since the attacks.

Efforts to restructure diplomatic engagements have hit a snag, with Iran asserting its unparalleled cooperation historically and pointing out that UN Security Council Resolution 2231 has expired without procedural adherence. China and Russia have backed Iran's stance, rejecting U.S.-European claims as lacking legal basis, according to sources close to the negotiations. The political context highlights strained U.S.-Iran and Israel-Iran relations post-June aggression, which Iran claims violated the Nuclear Non-Proliferation Treaty (NPT). Grossi faces accountability demands from Tehran for not condemning the attacks, adding another layer of complexity to the verification process.

In a related development, Eslami announced a "Nuclear Technology for Life" multimedia festival to promote domestic nuclear uses, aiming to bolster public support amid the tensions. Stakeholders, including the IAEA and Iran's nuclear industry, remain under scrutiny, with experts warning that delayed verifications could lead to escalated proxy conflicts unless U.S.-Iran negotiations restart. The historical context shows that pre-attack sites were IAEA-monitored with no diversion reports, but Iran distinguishes post-attack inspections as unprecedented. Without a deal, the impasse threatens to deepen regional instability, with Grossi prioritizing damaged-site access to prevent further deterioration in trust.
