A Royal Navy bomb disposal team have safely detonated a large World War II mine a mile off the coast of Falmouth.
The German device, 6ft (1.8m) by 3ft (91cm), which contained more than 700kg (1,540lb) of explosives, was towed out to sea from the Helford River.
About 50 boats gathered along a safety cordon a mile from the centre of the detonation site to watch.
Bomb disposal officer, Sid Lawrence said the bomb was "very, very powerful and very big".
