REAL COLD WAR: Crazy claim of undersea battle between Russia and aliens emerges

A SECRET "cold war" in the icy depths of the ocean has been taking place between aquatic aliens and the Russians, a new book has sensationally claimed.

Files detailing the mysterious USOs – unidentified submersible objects – are kept tightly under lock and key at the Kremlin, according to UFO authors Paul Stonehill and Philip Mantle.

The pair claim to have obtained leaked details of some of the encounters between Russian submarines and giant unexplained objects.

They believe the Russian government has attempted to debunk any witness who went public to hide evidence of what was going on beneath the waves.
