"The majority of civilian casualties were caused by shelling (eight killed and 16 injured), followed by gunfire (eight killed) and explosive remnants of war (ERW, one killed). The exact cause of one death and six other injuries was not determined." UNSMIL reported.

UNSMIL added that it had documented civilian casualties in Tripoli (16 killed and 22 injured), Benghazi (one killed) and Warshafana (one killed).

"Another 57 fighters died during the Tripoli fighting, while the civilian status of a further 12 fatalities could not be ascertained." UNSMIL indicated.
