The wreck of a German submarine that sank during World War One has been found in the North Sea and officials believe 23 bodies may be inside it.

The type UB-II submarine is said to be in good condition, lying at a depth of 30m (100ft) off the Belgian coast.
"The submarine is in such good condition that we reckon all the bodies are still on board," said West Flanders Governor Carl Decaluwé.

The vessel is thought to have been sunk by a mine.

Mr Decaluwé told reporters on Tuesday that the location of the wreck was being kept under wraps to prevent people going near it and to stop the submarine being looted or damaged.
