Czech divers have apparently been able to find and explore the wreck of an Austro-Hungarian submarine off the coast of Albania dating from WWI.
The wreck of the U16 had previously not been discovered or subject to a detailed exploration. The identity of the sub will have to be confirmed during further dives.
The submarine sank in mysterious circumstances in October 1916. It was probably sunk following an encounter with the Italian torpedo boat, Nembo.
