A dramatic collision in the North Sea has set ablaze an oil tanker and a cargo ship, raising fears of an environmental disaster.
On Monday, the US-flagged oil tanker MV Stena Immaculate collided with the Portuguese cargo ship MV Solong. The crash started a huge fire, which is still burning in the North Sea, about 10 miles (16km) off the coast of the busy Hull port and fishing centre.
