Putin has threatened the West with nuclear weapons over the war in Ukraine 

New satellite images show Russia's huge nuclear submarine, allegedly carrying 'apocalypse' and 'doomsday' weapons, lurking around the Barents Sea as fears grow that Vladimir Putin is planning to carry out a nuclear test.

The nearly 600ft Belgorod submarine has disappeared from its home base in the Arctic Circle and may be on its way to the Kara Sea to test the Poseidon nuke, a NATO warning note leaked over the weekend has suggested.

Satellite images publihsed by Naval News show the submarine is currently operating on the surface in the Arctic.
