A damaged building is pictured after clashes between rival militias, in an area at Alswani road in Tripoli on July 28. A rocket hit a fuel storage tank in a chaotic battle for Tripoli airport that has all but closed off international flights to Libya, leaving fire-fighters struggling to extinguish a giant conflagration. Two rival brigades of former rebels fighting for control of Tripoli International Airport have pounded each other's positions with Grad rockets, artillery fire and cannons for two weeks, turning the south of the capital into a battlefield.
