Foreign Minister Zarif and Secretary Pompeo engaged in a Twitter tit-for-tat regarding the humanitarian consequences of U.S. sanctions against Iran. After Zarif accused Pompeo of "openly threatening to starve Iranians", Pompeo argued that "the U.S. does not, and never did, sanction food and medicine". Zarif responded by saying that his U.S. counterpart "should either own what he says, or disown what [the] U.S. does. Can't have it both ways".
