The US was "caught off-guard" by air strikes against Islamist militia in Libya, a senior official has told the BBC.

The attacks on militia positions around Tripoli were reportedly carried out by the United Arab Emirates (UAE) from bases in Egypt. Egypt has denied any involvement and the UAE has not commented.

Footage shows militias guarding the entrance to the city's airport on Sunday, after the strikes failed to stop them taking it over.
