The UN Secretary General Antonio Guterres said the attack on Tripoli by Khalifa Haftar's forces led to the halt of the UN-led political process in Libya.
Guterres added in a report on Thursday that Haftar had conditioned control of his forces on Tripoli before entering in any negotiations or formation of a national unity government.
He hailed in the report, which he delivered to the Security Council, the initiative proposed by the Head of the Presidential Council Fayez Al-Sarraj in last June to revive the political process and then establish understandings for a constitutional basis for elections before the end of 2019
"The House of Representatives in Tobruk doesn't have full quorum and is holding sessions with 30 members present as other MPs - 40 ones - are convening in Tripoli. The decisions made in Tobruk with lack of quorum and using that for listing Muslim Brotherhood as terrorist group escalated the conflict since the Tripoli HoR members have voted as well to remove the post of the General Commander of Libyan Army held by Haftar." The Secretary General added.
He said Haftar's forces entry to Murzuq in southern Libya and their attempt to create parallel authorities fueled tribal tensions between Al-Ahali (Arabs) and Tubu residents, leading to the killing of 50 and damaging of 200 houses.
"Interim Government in eastern Libya is a defunct parallel government and has ordered authorities in Sabha not to take part in municipal elections held by the Government of National Accord." Guterres indicated.
The report said 111 civilians had been killed and 289 others injured since April 04, in addition to the displacement of over 120.000 people and the arbitrary detention of about 5000 migrants and refugees in Tripoli.
It also referred to the kidnapping of the HoR member Siham Sergiwa from her Benghazi house amid fears about the intentional silencing of women's voices and excluding them from political circles.
"I have fears that Libyan could be plunged in chaos and I confirm that there's no military solution in Libya. I therefore call for a ceasefire in the country and a return to the political process to regain stability and security in Libya." Guterres added.
