TRIPOLI, Oct. 6 (Xinhua) -- Clashes between two armed groups affiliated with the UN-backed government broke out Friday in Libya's capital Tripoli, killing two and injuring three others, a security source said.
"Clashes broke out Friday between the Battalion 42 and the Central Security Battalion in southern Tripoli, killing two people and wounding three," the source, who asked to remain anonymous, told Xinhua.
The clashes came after the two battalions kidnapped each other's members on Thursday night, with Battalion 42 opening fire first by attacking the headquarters of the Central Security Battalion to free its detained members.
The clashes, which lasted several hours, have already ceased, the source noted.
In Tripoli, clashes between armed groups over disputed ownership of military and security headquarters or the control zones in the capital, take place from time to time.
Libya has remained in chaos following the 2011 uprising that toppled former leader Muammar Gaddafi. The country is struggling to make a democratic transition amid political division and unrest, as well as dominance of armed groups and militias with shifting loyalties.
