WASHINGTON/DUBAI — The U.S. military said it launched another round of strikes on Iran after the Islamic Revolutionary Guard Corps struck a container ship traveling through the Strait of Hormuz on Sunday. A series of attacks between the U.S. and Iran over the past several days led President Donald Trump to declare the end of a ceasefire meant to halt the fighting that the U.S. and Israel began on February 28, though Trump has left the door open to continued negotiations. Iran said it closed the vital Strait of Hormuz after firing a warning shot that struck a vessel traveling on an unapproved route. It warned that any retaliation over the incident would be met with a "severe response." U.S. Central Command identified the vessel as the M/V GFS Galaxy, a Cyprus-flagged container ship, saying it suffered significant engine-room damage and that a civilian crew member was missing.
