Iran has to 'walk away' from uranium enrichment and long-range missile development and it should allow Americans to inspect its facilities, U.S. Secretary of State Marco Rubio said on Thursday as a round of nuclear talks was postponed.
Rubio's comments underscore the major remaining divisions in talks between the countries to resolve the long-running dispute over Iran's nuclear programme, with U.S. President Donald Trump threatening to bomb Iran if there is no agreement.
