The attack was carried out by a jeep fitted with a bomb, which targeted members of the 127th Infantry Brigade that was part of the Juffra Operations Room, Ahmed Mesmari, spokesperson for the eastern army said.
Libya Herald, citing the army official, notes that the attack took place at a checkpoint manned by the army, 22 km west of the central Libyan city of Waddan on the road towards Tripoli.
Two other army personnel were injured in the attack.
The LNA led by self-style Khalifar Haftar controls large swaths of the Libyan territory in collaboration with the country’s internationally recognized House of Representatives, located in the eastern city of Tobruk, and the Beida-based administration.
Haftar and his army have declared victory over jihadists in the eastern part of country and around Benghazi but the terror group still stages sporadic attacks against the LNA.
Haftar, former Gaddafi’s key aid, is eager to become the country’s future president. He has endorsed UN-planned elections believed to take place late this year. The army commander has however warned that he would not accept rigged results and that he would ask a national mandate if things go chaotic.
