VIENNA/WASHINGTON (Reuters) -Iran has begun the process of producing enriched uranium metal, the U.N. atomic watchdog said on Tuesday, a move that could help it develop a nuclear weapon and that three European powers said threatened talks to revive the 2015 Iran nuclear deal.

Iran's steps, which were disclosed by the International Atomic Energy Agency and which Tehran said aimed to develop fuel for a research reactor, also drew criticism from the United States, which called them an "unfortunate step backwards."
