TRIPOLI, LIBYA - JULY 16: Damaged helicopters is seen at the Tripoli international airport in Tripoli, Libya on July 16, 2014. Tripoli international airport came under rocket fire Wednesday for a fourth straight day and attacks aimed at ousting anti-Islamist fighters who control the facility. Islamist militias have since Sunday unleashed dozens of rockets at Tripoli airport, damaging around a dozen planes and closing down Libya's main air link with the outside world.
