Five people were killed and eight wounded when a suicide bomber from ISIS drove of a car laden with explosives into a checkpoint on the outskirts of the city of Misrata in western Libya.
The attack that damaged numerous nearby shops and vehicles was claimed by ISIS through Twitter posts.
Government loyal forces from Misrata have been fighting ISIS militants in central Libya since March in response to which ISIS began a series of car bombings on checkpoints on the outskirts of the city.
Libya is divided between two feuding parliamentary bodies, with Western Libya being under the control of the Tripoli-based General National Council (GNC) administration and the easternmost area near the Egyptian border falling under the command of the rival House of Representatives (HoR) body, which founded last August.
"We will support all army, police and revolutionary forces to fight and chase those apostates who have come to Libya claiming they are representing Islam," GNC Prime Minister Khalifa Ghwell told reuters regarding the blast.
ISIS forces have been able to establish a presence in eastern and central Libya due to the lack of order in the region, establishing themselves in the cities of Derna and Sirte.
