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 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.

U.K. police say the Solong cargo ship's captain, identified by the vessel's owner as a Russian national, was detained on suspicion of negligent manslaughter.

Fears of an environmental disaster eased on Wednesday, two days after a container ship ploughed into a stationary U.S. fuel tanker off northeast England, as the vessel's owner said the detained captain was a Russian national.

The captain of the Solong cargo ship has been detained following a collision with a US-flagged tanker, the Stena Immaculate, off the English coast. The incident, which occurred in the North Sea, has sparked concerns over environmental damage due to a jet fuel spill.

The under-arrest captain of a container ship which crashed into a US oil tanker in the North Sea is Russian, the vessel's owner has said. Solong struck the Stena Immaculate off the east coast of Yorkshire on Monday morning.
