Anchor from 'Blackbeard's ship' raised from ocean

An anchor from what is said to be the wreck of the ship belonging to Blackbeard has been retrieved from the water off the coast of North Carolina in the US.

The anchor, weighing more than one tonne (2,200lb), is one of the biggest artefacts salvaged from what is believed to be the Queen Anne's Revenge - the English pirate's flagship.
