(CNN)A US Navy sailor was serving as an exchange officer onboard the Norwegian naval frigate that was struck by a freighter and has now almost entirely sunk, according to the U.S. Navy and the Norwegian Ministry of Defense.
The Norwegian government’s Accident Investigation Board is investigating the incident and the US has been informed that the American sailor may be part of that investigation. The sailor has not been identified and his exact role on the ship is unknown.
A large hole was torn into the side of KNM Helge Ingstad when it collided with a Malta-registered oil tanker, Sola TS, in the early hours of November 8.
