On July 30, the Mercer Street, a Japanese-owned tanker, was attacked by multiple drones off the Omani coast, killing a British national and a Romanian.

The Liberian-flagged vessel, though owned by a Japanese shipping company, is managed by London-based Zodiac Maritime, which is owned by a wealthy Israeli family.

The U.S. 5th Fleet determined after a visual inspection "that a UAV-style attack had occurred.” The Mercer Street was eventually escorted to safer waters by the U.S. Navy, including the USS Ronald Reagan aircraft carrier.
