Most of the jet fuel onboard the U.S.-flagged tanker Stena Immaculate that was hit by a container ship in a collision off Britain's coast remains contained and only two of the vessel's 18 fuel tanks have leaked,

The revelation comes as the owner of the Solong, Ernst Russ, confirmed the captain who has been arrested by Humberside Police is a Russian national. The 59-year-old man arrested on suspicion of gross negligence manslaughter after a collision between a tanker and a cargo ship in the North Sea remains in custody, police have said.

The tanker that was hit at anchor off the coast of England in the North Sea was under contract by Military Sealift Command in support of the Defense Logistics Agency, USNI News has learned. The U.S.-flagged MV Stena Immaculate was at anchor when Portugeuse-flagged container ship MV Solong struck the tanker at about 5:48 a.
