The United States has announced sanctions targeting what it describes as an Iranian 'shipping empire.' According to U.S. officials, this network is controlled by Mohammad Hossein Shamkhani, the son of a high-ranking advisor to Iran's Supreme Leader. The sanctions aim to disrupt the financial activities of this shipping network and curtail its ability to support activities deemed detrimental by the U.S. government. This move represents the latest effort by the U.S. to pressure Iran through economic measures.
