A man has been arrested in Germany after a stash of guns, ammunition and bomb-making material was found in a nuclear-proof bunker he built under his house.

Two submachine guns along with 80 rifles and 60 handguns have been confiscated.

The man also had 20,000 rounds of ammunition, and 40 kilos of materials to make explosives.

He'd built the shelter by reinforcing the basement of his family home in Bavaria, because he was afraid of an attack from Russia.
