BP has announced that it is withdrawing some non-essential overseas staff from Libya, in what it described as a "precautionary measure".
The company's Libyan staff will remain in the country.
The British Foreign Office withdrew embassy staff from Tripoli late last week.
BP announced last year that it would start its $2 billion deep-sea drilling programme in 2013 under its joint Exploration and Production (E&P) agreement with the National Oil Corporation (NOC).
