Both pilots flying a Libya Dawn MiG-23UB fighter aircraft were killed when they were shot down on Monday whilst attacking an air base.
The aircraft was attacking Zintan (Al Watiya) airport when it was shot down by the Libyan National Army with a surface-to-air missile, believed to be an Igla-S, reports Air Forces Daily.
Libya Dawn apparently carried out air strikes against Zintan on 17 February, using aircraft from Mitiga Airbase in Tripoli, which it controls. The base is home to several MiG-23s. Most of the Libyan Air Force is allied with the Libyan National Army, according to IHS Janes.
