Transatlantic Rift Laid Bare as U.S. Rebukes EU Allies over Iran Deal

The United States has called on Europe to abandon the 2015 nuclear deal with Iran, which Washington pulled out of last year. At a conference in Warsaw attended by more than 60 nations, U.S. Vice President Mike Pence accused European allies of trying to break American sanctions against what he called Iran's 'murderous revolutionary regime.' Several EU states have refused to attend the meeting, as Henry Ridgwell reports.
