US blocks Iranian nuclear chief from UN watchdog meeting

Tehran says Washington violated international law by preventing Mohammad Eslami from attending the IAEA event in Vienna The US has violated international law by pressuring Austria to prevent Iran’s nuclear chief from attending a UN nuclear watchdog event in Vienna, Tehran has said. Mohammad Eslami, head of the Atomic Energy Organization of Iran (AEOI), was blocked from participating in an International Atomic Energy Agency (IAEA) meeting this week after the US refused to grant him a sanctions waiver, Iranian media reported. “Such acts violate the host country’s obligations under the Headquarters Agreement between the IAEA and Austria. That agreement obliged the host government to take all necessary measures to facilitate the entry of representatives of Member States into Austrian territory,” Iran’s mission in Vienna said in a statement on X on Monday.
