Tripoli's Special Deterrence Force (SDF) said Mitiga Airport is secure after the clashes had ended, adding that its personnel are in control of the airport and flight had resumed.
SDF added on its Facebook page on Wednesday that most of the "criminals" behind the fighting and security violations around the airport were arrested.
It also offered condolences to the families of the victims of the vicious clashes, which it described as fighting evil powers and criminals who are destabilizing Libya and Libyans' security.
Five civilians were killed and over 15 others were injured when a rocket fell on a beach opposite to the airport on Tuesday, leading to the suspension of flights in the airport, before the SDF had interfered and attacked whom it described the outlaws.
For a short time, flights to and from Mitiga airport had been rescheduled to Misrata airport.
The UN-proposed government's Interior Ministry said investigation is underway to find out the truth about last night's criminal act that is done by an outlaw group.
The Interior Minister, Aref Al-Khoja paid a visit to the post-clashes scene in Mitiga airport after the SDF had declared it secure. He vowed to hand the administration of the airport to relevant authorities soon in order to run it properly.
