TRIPOLI, Feb. 1 (Xinhua) -- Violence in Libya has killed 39 civilians and wounded 63 others in January, the Support Mission in Libya (UNSMIL) said Thursday.

The UNSMIL documented 102 civilian casualties during the conduct of hostilities across Libya in the whole January, which is "a sharp rise from previous months," the mission said in a latest report.

The figures for casualties only include "persons killed or injured in the course of hostilities and who were not directly participating in the hostilities," it said.

The report also pointed out that most of the casualties were caused by car bombs, unexploded ordnance, gunfire and shelling.

Libya has been plagued by insecurity and chaos since the overthrow of Muammar Gaddafi's regime in 2011.
