Iran accuses US of violating international law by blocking nuclear chief from IAEA meeting

The US has violated international law by pressuring Austria to prevent Iran’s nuclear chief from attending a UN nuclear watchdog event in Vienna, Iran has said.

Mohammed 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.

Reza Najafi, Iran’s envoy to international organizations in Vienna, argued that the move was “a serious violation” of the country’s rights as an IAEA member. The agency is tasked with monitoring nuclear activities and compliance with nuclear non-proliferation obligations.
