As Trump Imposes New Sanctions, Iran Says U.S. Has "Permanently Closed Path to Diplomacy"

President Trump announced Monday his administration is imposing a new round of sanctions on Iran, targeting several prominent Iranians including Supreme Leader Ayatollah Ali Khamenei and Iran's top diplomat, Foreign Minister Mohammad Javad Zarif. Iran said the move "permanently closed the path to diplomacy" between Iran and the United States. The latest tension comes after the downing of a U.S. drone by Iran on Thursday. Iran maintains the drone had entered its airspace, while the U.S. claims the drone was in international waters. The U.S. military prepared to directly attack Iran in retaliation, but Trump reportedly called off the bombing at the last minute.
