A masked Libyan gunman stands on a street in the eastern city of Benghazi, early on July 29, 2014, as violence has hit the city, cradle of the 2011 revolution, where weekend fighting between the army and Islamists killed 28 people, mostly soldiers. Militiamen are also battling in the capital Tripoli to flush out fellow former rebels from the hill town of Zintan, southwest of Tripoli, who have controlled the airport for three years.
