Air traffic resumed at Tripoli’s Mitiga airport on Tuesday after a brief closure prompted by renewed clashes in the Libyan capital. Rockets were fired at the facility’s directions, forcing its initial closure, officials said. Mitiga airport, a former air base used for commercial flights since the main international airport was destroyed in 2014 by militia fighting, said in a notice that traffic was resuming. It has closed and opened several times since the flare-up in violence in late August.
