The U.S. Treasury chief has warned that Iran Airlines will be shut down if sanctions are not lifted. The statement comes as part of ongoing tensions between the United States and Iran. The Treasury official emphasized that the decision would be enforced if diplomatic efforts fail. Iran has repeatedly denied allegations of supporting terrorism and has called the sanctions unjust. The move follows recent reports of increased U.S. Pressure on Iranian financial institutions. The situation remains under close watch as both sides prepare for potential further actions.
