Iran sanctions to 'snap back' if it violates nuclear deal - diplomats

VIENNA (Reuters) - Iran has accepted a so-called "snapback" plan that will restore sanctions in 65 days if it violates a deal agreed with six world powers to curb the country's nuclear programme, diplomats told Reuters on Tuesday. The diplomats said a U.N. arms embargo would remain in place for five years and U.N. missile sanctions would stay in place for eight years.
