The
United States announced Monday it would halt
sanctions waivers for Iran's Fordow plant, ending a key part of a landmark
nuclear deal after Tehran said it had resumed enrichment activities.
The move is intended to end
Russian and European cooperation with
Iran on the once-secret site, which was supposed to become a civilian research center under the 2015 agreement.
Secretary of State
Mike Pompeo pointed to Iranian President Hassan Rouhani's announcement of renewed activity at Fordow -- a series of steps taken by Tehran as it presses European allies to make good on sanctions relief promised for compliance.
