“There is no possibility whatsoever that the ship sank due to an internal explosion or a collision with a reef. I guarantee that,” a navy lieutenant was quoted as saying by participants in a briefing session organized by the Navy’s Second Fleet Command in Pyeongtaek, Gyeonggi Province — the home port of the ill-fated ship.
