UK tells Britons to leave Benghazi in Libya immediately

British nationals should leave the Libyan city of Benghazi immediately "in response to a specific threat to Westerners", the Foreign Office says.

It said the British Embassy in Tripoli had been in contact with British nationals whose details it had.

Officials could not comment further on the nature of the threat, but said there was new travel advice for Libya.
