A mine laid by British forces off the Dorset coast during World War Two has been detonated.
The device was discovered close to the breakwater off Portland on Wednesday and a warning was issued to shipping.
A Royal Navy bomb disposal team moved it further out to sea where it was destroyed.
It is believed to have been laid as part of defence measures to prevent German vessels entering British waters during World War Two.
Lt Peter Davis of the Royal Navy said the bomb had been a “random find” by divers during a seabed survey.
“Given the age of the ordnance, the explosive charge within the mine is likely to have degraded over time.”
