John Kerry: Libya unrest 'presents real risk' to US embassy

The US has temporarily evacuated its staff from the Libyan capital Tripoli over security concerns.

Personnel, including marine guards providing security to the embassy, have been transferred to Tunisia.

Secretary of State John Kerry said there was a lot of violence in the area surrounding the embassy that presented a "very real risk" to staff.

The move comes amid fierce clashes between rival militias in the capital, with intense fighting at Tripoli airport.
