Paranormal investigators claim ‘leaked’ ufo pictures taken from US submarine show vessels hovering over Atlantic Ocean.

Researchers believe the black and white images were taken from the USS Trepang SSN 674 submarine in March 1971 and show evidence of alien lifeforms.

The pictures are said to have been taken from the US submarine on its journey between Iceland and islands of the coast on Norway.

Alex Mistretta, an author who specialises in paranormal exploration, looked into the images after they appeared in French magazine Top secret after an alleged leak.
