The United Nations Fact-Finding Mission siad in a report on Monday it had found evidence of mass graves' crimes  against civilians in Tarhouna, southeast of Tripoli, between 2016 and 2020. 

"Our investigations have established that all parties to the conflicts, including third States, foreign fighters and mercenaries, have violated international humanitarian law, in particular the principles of proportionality and distinction, and some have also committed war crimes,” said Mohamed Auajjar, Chair of the Fact-Finding Mission.

Auajjar said they couldn't just yet provide the names of the people involved in the crimes, urging the Security Council to extend the work of the Fact-Finding Mission to further investigate the incidents. 

"The Fact-Finding Mission has identified individuals and groups (both Libyans and foreign actors) who may bear responsibility for the violations, abuses and crimes committed in Libya since 2016 and this confidential list will remain so, until the need arises for its publication or sharing with other accountability mechanisms." 

It said the first visit focused on Tripoli and its suburbs, adding that Benghazi will be next for further investigation, and reiterated that it has nothing to do with who is going to run for elections in Libya as it gathers evidence regardless of the identity of the perpetrators. 

The UN Fact-Finding Mission was established by the UN Human Rights Council resolution 43/39 to probe violations and crimes across Libya since 2016.
