IAEA chief confirms agency has 'no proof' Iran building nuclear bomb

The Director General of the International Atomic Energy Agency (IAEA), Rafael Grossi, said on 17 June that there is “no proof” that Iran has been working toward the development of a nuclear weapon. 

“What we informed and what we reported was that we did not have – as in coincidence with some of the sources you mentioned there, that we did not have any proof a systematic effort to move into a nuclear weapon,” Grossi said in an interview with CNN’s Christiane Amanpour. 

The IAEA chief also said he is not aware of whether or not any secret activities were carried out by Iran without the knowledge of the UN watchdog.
