Suspected unexploded weapon found on Cornwall's Porthmeor Beach
Lifeguards have found what is believed to be a section of an unexploded weapon on a Cornish beach.
The object, which witnesses have said looks like a corroded depth charge - an anti-submarine warfare weapon - has been found at Porthmeor Beach, in St Ives, Falmouth Coastguard has said.
Police have set up a 100m (328ft) cordon and a Royal Navy bomb disposal team has been called out.
It is being treated as a low-risk incident, a coastguard spokesman added.
A bomb disposal team is expected to attend at about 21:00 BST during low tide when the object will be visible in the sea again, the spokesman said.
