A container ship hit a stationary U.S.-flagged oil tanker on Monday, forcing the crews to abandon ship. A search for a missing crew member ended Monday night.

An oil tanker reportedly on fire in the North Sea after colliding with a cargo vessel. Lifeboats and a coastguard helicopter were called to the collision in the Humber Estuary on Monday morning, believed to involve a US-flagged tanker called the MV Stena Immaculate.

All 23 people on the tanker were rescued along with 13 of 14 crew members from the Solong but Filipino national Mark Angelo Pernia could not be located.

The captain arrested in a crash into a U.S.-flagged tanker off the coast of England is a Russian national, the owner of the vessel said.

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.
