(London Daily Mail) Divers exploring a 'UFO-shaped' object in the Baltic sea say that the strange, curved object might be a Nazi device lost beneath the waves since the end of the Second World War.
Sonar scans have shown that the device, raised 10ft above the seabed and measuring 200ft by 25ft, could be the base of an anti-submarine weapon.
The weapon was built with wire mesh which could have baffled submarine radar, leading enemy craft to crash - much in the same way as turning out a lighthouse could be used as a weapon against shipping.

But now former Swedish naval officer and WWII expert Anders Autellus has revealed that the structure - measuring 200ft by 25ft - could be the base of a device designed to block British and Russian submarine movements in the area.
The huge steel-and-concrete structure could be one of the most important historical finds in years.
