The head of the International Atomic Energy Agency (IAEA) said on Wednesday that Iran is “restricting” cooperation with his inspection teams over its nuclear programme as a way of retaliating to criticism.Director-General Mariano Grossi spoke to UN News’s Cristina Silveiro about the “complex logic” behind the move to bar multiple inspectors there, the safety of nuclear power plants in Ukraine amid Russia’s invasion, and the latest on the Fukushima nuclear wastewater issue.
