TRIPOLI Libya (Reuters) - Libyan militia fighters with anti aircraft guns and mortars fanned out on Tuesday across Tripoli's airport, transformed into a battlefield by two days of fighting that has cut the Libyan capital off from the outside world.
U.S. Secretary of State John Kerry said Washington was working to help end to violence that has brought the north African country to the edge of chaos three years after the uprising that toppled dictator Muammar Gaddafi.
