The IRGC Navy fired at least 5 cruise missiles at ships in the Strait of Hormuz on September 18. This military action follows a formal declaration from Iran that the strategic waterway will remain closed until U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu are "brought down from power."

A U.S. blockade in the region has redirected 105 commercial vessels heading to or from Iranian ports, U.S. Central Command reported. More than 30 million barrels of Iranian crude oil have been kept in the Persian Gulf due to the restrictions.
