"About nine" World War Two explosives have been washed up on a beach in Essex following recent storms, Thames Coastguard have said.
Experts from the Royal Navy carried out controlled explosions on the anti-aircraft shells at Westcliff-on-Sea at about 09:45 GMT.
They were called in by coastguards, after a man walking on the beach on Sunday morning spotted the explosives.
They were identified as anti-aircraft shells by the navy experts.
Thames Coastguard said the shells, which were corroded but still live, were found at low water at Ray Gut channel, about half a mile (800m) away from Westcliff seafront.
