Press TV, Iran’s propaganda outfit in the U.S., conducted an interview with Reza Najafi, Iran’s ambassador to the International Atomic Energy Agency (IAEA). According to this outlet, Najafi was asked about the IAEA’s role in the potential deal.
“The agency as a professional organization, indeed, should do a professional work. It means — only from the technical point of view — reporting what has been done by Iran. Of course Iran under the Joint Plan of Action, agreed in Geneva, agreed to implement some voluntary measures.” [Bold mine]
These voluntary measures have been implemented, constantly, and it was reported by the agency, and confirmed and verified.
