Smoke billows near a road leading to Tripoli international airport during clashes between Islamist-led militiamen and rival ex-rebels who control the facility, on July 20, 2014, in the Libyan capital Tripoli. The fighting has forced a halt to all flights and caused extensive damage to planes and airport infrastructure, with aviation officials saying Tripoli airport could stay closed for months.
