A CIA document has revealed that two nuclear submarines collided in a sea loch just off the west coast of Scotland more than 40 years ago.

The top secret memo, which has just been declassified, tells how a US submarine collided with a Russian vessel near Holy Loch in November 1974.
The cable marked "Secret eyes only" was sent to US secretary of state Henry Kissinger.
The memo says there were no reports of the extent of the damage.
It is understood the US submarine was taken back to its base with significant damage to its hull.
