The Trump administration on Wednesday placed additional sanctions on Iran as part of a sprawling economic pressure campaign during the war, this time targeting the country's newly-created agency that is trying to control shipping through the Strait of Hormuz. The move, first reported by The Associated Press, is the latest US effort to use economic leverage on top of military action to push Iran's leadership into an agreement to end the war and open the waterway where a fifth of the world's oil and natural gas normally passes. President Donald Trump has said a deal is imminent, but talks are ongoing.
