The head of Iran’s Atomic Energy Organization said Saturday that his country will not exceed 60 percent enrichment of uranium, even if it cannot agree with world powers on a return to the 2015 nuclear deal.

Asked by Russia Sputnik news agency about the possibility enrichment levels would rise further, Mohammad Eslami responded, “No.”

He further asserted that “All our nuclear activities are carried out according to the agreements, statutes and regulations of the International Atomic Energy Agency.”
