SECRET American Central Intelligence Agency files have revealed that Soviet and US nuclear submarines collided off the Holy Loch 40 years ago.
An expert, quoted in a national newspaper on Wednesday, claimed the incident was so serious it could have led to a third world war.
Crash details have been confirmed in a US military cable released by the CIA, marked ‘Secret eyes only’ and sent to Henry Kissinger, at the time US secretary of state, by Brent Scowcroft, a national security adviser to President Gerald Ford, on November 3, 1974.
