Moscow has urged the United States not to take any rash steps against Iran that would spoil the nuclear deal, Russian Deputy Foreign Minister Sergey Ryabkov said on Tuesday. US President Donald Trump is expected to announce a decision soon on whether to withdraw from the Iran agreement between Tehran and world powers. There are no grounds to believe that Iran is on a path to creating a nuclear bomb, Ryabkov told RBC. He said Tehran had agreed on the deal voluntarily, adding that now “we see attempts on the part of the Trump administration to revise it and cross out what has been achieved, under an absolutely contrived pretext.”
