UK urges Britons to leave Libya's Benghazi over threat

TRIPOLI/LONDON (Reuters) - Britain urged its nationals to leave the eastern Libyan city of Benghazi on Thursday, citing a "specific and imminent" threat to Westerners days after a deadly attack by Islamist militants in neighbouring Algeria.

Britain's Foreign Office declined to give details of the nature of the threat, but has warned in the past of the long reach of al Qaeda in the Islamic Maghreb, the North African wing of al Qaeda.
