The most catastrophic war of the 20th century may have claimed another victim, after the detonation of what appears to have been a World War II shell in a German town on Monday night.

One man died and another was seriously injured in the incident which took place in the small town of Niemegk, near Berlin. On Wednesday, Christoph Lange, spokesman for the public prosecutor's office in Potsdam, told reporters that the explosion had probably been caused by a World War II shell. However, the police have still not confirmed exactly what type of explosive was involved in the deadly blast.

Many Germans have made a hobby of searching for and collecting World War II relics scattered across the country. The victims, two good friends, are reported to have acquired a metal detector for just that purpose.
