A secret Nazi military base in the Arctic has been discovered by Russian scientists.
The site is located on the island of Alexandra Land 1,000km from the North Pole and was constructed in 1942, a year after Adolf Hitler invaded Russia.
The base was abandoned when the scientists stationed there were poisoned by polar bear meat in 1944.
More than 500 objects have been found, including a batch of well preserved documents.
The ruins of bunkers and other relics dating from the Second World War have been discovered in a good condition having been preserved by the cold weather.
It is said the mysterious base was used as a meteorological station, but many believe the base had other secret missions.
