A World War II parachute mine that was dredged up by a fishing boat has been detonated off the east Kent coast.
Bomb disposal teams tried to blow up the device twice on Friday, but both attempts failed. It finally exploded on Saturday morning.
The fishing boat crew raised the alert on Friday after dredging up the unexploded bomb in the vessel's fishing nets in the Thames Estuary.
Bomb disposal experts moved it to the waters off Margate on Friday.
The bomb was marked in the water and ships were warned to stay clear overnight.
Dover Coastguard said the device, believed to be a 1,000lb bomb, was successfully detonated by a Royal Navy bomb disposal team on Saturday.
Coastguard spokesman Mr Binks said the fishing vessel had found a similar device in the past.
The Germans used parachute mines against British targets in 1940 and 1941.
