On Saturday, the European Union’s energy chief tried to reassure Iran that the bloc remained committed to the nuclear deal with Tehran, despite U.S. President Donald Trump’s decision to exit the accord and reimpose sanctions. Iran’s nuclear chief Ali Salehi said his country hoped the EU would manage to salvage the 2015 deal. Since Trump’s announcement on May 8 about the U.S. exit, European countries have said they will try to keep Iran’s oil and investment flowing.
