Violence in Libya killed four civilians and injured 27 others in April, the UN Support Mission in the North African country said Tuesday, Xinhua reported.
"From April 1-30, 2018, the United Nations Support Mission in Libya (UNSMIL) documented 31 civilian casualties - four deaths and 27 injuries - during the conduct of hostilities across Libya," said a report by UNSMIL.
Three men and one boy were killed and 19 men, five women, two boys and one girl were injured, said the report.
Shelling, gunfire, explosive remnants of war and vehicle-borne improvised explosive devices caused the most civilian casualties, according to the report.
The report demanded all fighting parties in Libya to "cease the use of mortars and other indirect weapons and imprecise aerial bombardments in civilian-populated areas, and not place fighters or other military objectives in populated areas."
"All executions of captives must cease and all those captured including fighters must be treated humanely in all circumstances. Murdering or torturing captives is also a war crime, regardless of what the captive may be accused of," the report added.
Since the 2011 uprising that toppled former leader Muammar Gaddafi's regime, Libya has been plagued with escalating violence and unrest, as well as political division.
