A BBC inspection of the oil tanker involved in the collision on North Sea has revealed the extent of the damage to the vessel. Justin Rowlatt said he could see a "huge gash" down the side of the Stena Immaculate from when the Portuguese-flagged cargo ship Solong collided with it off the East Yorkshire coast on 10 March.

An environmental group in the U.K. says the North Sea tanker collision could become a "disaster in really important protected areas."
