The Secretary General of the United Nations Antonio Guterres has spoken on the phone with the Head of the Libyan Presidential Council Fayez Al-Sarraj to express shock at the unearthing of mass graves in Tarhouna and the discovery of mines planted in south Tripoli's residential areas, where Khalifa Haftar's forces were positioned.

The media office of Al-Sarraj said Guterres had called for inclusive and transparent investigations to being the perpetrators to justice as per international humanitarian law and international law for human rights, welcoming the UN Human Rights Council's decision to send a fact-finding mission to Libya and adding that the UN was working steadily to appoint a new envoy to Libya to revive the political process.

Meanwhile, Al-Sarraj said Haftar was defeated after he waged war on Tripoli over a year ago in the presence of Guterres in the Libyan capital, adding that now the world can see that Haftar's military project is crumbling due to the bravery of the Libyan Army forces and the just cause they represent.

He also said that Haftar's war left destruction and massive violations as he and his backers are still having their impunity.

"The Libyan Army will continue to defend the sovereignty of the country against illegitimate external interventions and will eliminate putschists and criminals across the country. We won't allow mercenaries and terrorists to control Libyan oil resources, so reopening oil production is not up for negotiations at all." Al-Sarraj added.

He reiterated his position that has been with the political solution from the start, adding that the international community should now take a different approach to the crisis as Haftar cannot be considered as a political partner or a legitimate representative anymore.

Al-Sarraj told Guterres that the only solution to the Libyan crisis is via the Libyan people and the end of the fragile transitional phase by general elections and a permanent constitution.
