The U.S. has sunk an Iranian warship amid the unfolding conflict in the Middle East, U.S. Defense Secretary Pete Hegseth says. Speaking to reporters at the Pentagon Wednesday, Hegseth showed an unclassified video capturing a strike on what has been identified as Iran’s IRIS Dena vessel in the Indian Ocean. Hegseth described it as a “quiet death,” noting that it was the first torpedo sinking since the Second World War.
