Mitiga Airport authorities in the Libyan capital announced that air traffic had resumed after being halted following a recent air strike.
Earlier, the airport authorities posted to Facebook that air traffic had been suspended after an air strike.
No further information was available.
The reported attack comes after another suspension in the airport's work, which followed the last air strike on 30 June.
On 6 June the airport reported one of its runways had been hit by an aircraft belonging to the Libyan National Army (LNA).
In early June, the Libyan National Army (LNA) claimed it had repelled an offensive launched by rival the forces of the Government of National Accord (GNA) on the Tripoli airport. Fifteen GNA combatants, including six mercenaries from Chad, were killed in the clashes.
Armed skirmishes in Libya escalated on 4 April, when LNA leader Field Marshal Khalifa Haftar ordered his troops to advance on Tripoli to free it from what he deemed to be terrorists. After the LNA gained control over several cities near Tripoli, the rival UN-backed Government of National Accord (GNA) announced a counteroffensive, dubbed the Volcano of Rage.
Libya is currently a duopoly, with the eastern part of the country controlled by the parliament and the LNA, while the GNA controls the west. The United Nations said in late June that 739 people had been killed and 4,407 wounded during hostilities in Tripoli since April.
