A fact-finding mission to Libya has been established by the United Nations' top rights body after prosecutors from the International Criminal Court said that mass graves discovered recently may constitute war crimes.

The UN Human Rights Council adopted by consensus a resolution strongly condemning all acts of violence in Libya and urging UN rights chief MICHELLE BACHELET to dispatch a fact-finding mission to the North African country. 

Libya, a major oil producer, has been mired in turmoil since 2011, when longtime ruler MUAMMAR GADDAFI was toppled in a NATO-backed uprising.
