Rival Libyan militias clash in Tripoli, Benghazi

Heavy black smoke rose over southern Tripoli on Thursday after rival militias exchanged artillery and rocket fire in a battle over the Libyan capital's airport that has killed more than 50 people in nearly a fortnight of fighting.
Sporadic blasts echoed across the city from the morning in clashes that have deepened fears of post-war Libya becoming a failed state, with a fragile government unable to control heavily armed brigades battling for power.
Fighting in the capital and the eastern city of Benghazi is the heaviest since the 2011 war that ousted Muammar Gaddafi. It has closed most international flights to Libya and has prompted the United States to pull out embassy staff.
A health ministry official in Tripoli was unable to provide details of Thursday's casualties because he could not contact hospital staff in the area. One local doctor said at least 30 injured people were at his Tripoli hospital on Wednesday.
Mitiga hospital in Tripoli said it was in an emergency situation because of a lack of resources and the inability of many employees to get to work due to the fighting and gasoline shortages, state news agency LANA reported.
At least nine people were killed and 19 wounded, mostly civilians, in heavy clashes overnight in Benghazi as government forces tried to oust Islamist militants holed up in Libya's eastern port city, medical sources said on Thursday.
Most gas stations in Tripoli have closed since the fighting erupted over the airport. Hundreds of cars have been left for days in huge lines at different stations waiting for fuel.
The National Oil Corporation (NOC) said in a statement the gasoline crisis was mainly a security problem and was not caused by a lack of supplies.
Two main rival militias in Tripoli have exchanged fire with Grad rockets, shells and anti-aircraft cannons for control of the main airport for nearly two weeks, damaging aircraft there, and shutting down most international flights.
Turkish Foreign Minister Ahmet Davutoglu said on Thursday Turkey may evacuate its embassy in Tripoli, a day after his ministry advised all Turkish citizens to leave the North African country due to the worsening security situation.
