IAEA chief: 'Iran’s ability to enrich uranium has expanded'

International Atomic Energy Agency (IAEA) Director Rafael Grossi said on Wednesday that his agency is still trying to clarify answers from Iran on outstanding questions involving traces of human-made enriched uranium at three sites in the country.

Speaking to The Associated Press, Grossi acknowledged that Iran’s ability to enrich uranium since the collapse of the 2015 nuclear deal had expanded as it uses more-advanced centrifuges.
