Three or five of Iran's IRGC Navy gunboats unsuccessfully attempt to seize control of British oil tanker "British Heritage" in the Persian Gulf, according to UK's Ministry of Defense as well as two anonymous U.S. officials. The Royal Navy's HMS "Montrose" reportedly warns the boats to back away from the BP Shipping-owned tanker, which they do. The incident is allegedly captured on a U.S. aircraft's camera.
