Anti-submarine war games off the Westcountry coast were the "most probable" cause for the mass stranding of 26 dolphins on the region's coast, scientists have concluded.
The pod of dolphins beached themselves at four separate locations around the Percuil River, near Falmouth, in June 2008 after an international military exercise involving surface ships and a submarine.
At the time, conservationists said they believed the worst mass stranding of the marine mammals in UK waters was the result of the dolphins being panicked by an underwater disturbance.
