"LNA repelled an armed attack by [GNA armed] groups… on Tripoli airport on Sunday morning," he said.
Obeidi noted that 15 GNA militants, including six mercenaries from Chad, were killed in the clash.
In April, Khalifa Haftar, the head of the LNA, launched an offensive to retake Tripoli from control of the internationally-recognised Government of National Accord (GNA).

The forces loyal to the GNA announced a counteroffensive, dubbed Volcano of Rage.
