Iran's Nuclear Chief Blocked from Vienna Meeting, Summons Austrian Envoy

Iran's nuclear chief, Ali Akbar Salehi, was barred from attending a Vienna meeting on September 14, 2026, according to Arab News. The decision came amid ongoing tensions over Iran's nuclear program and its participation in international talks. In response, Iran summoned the Austrian envoy to protest the blockage, signaling a sharp deterioration in bilateral relations. The exact reasons for the blockage remain unclear, though sources suggest it relates to broader diplomatic disagreements.
