The U.N. Security Council Wednesday adopted a resolution calling for a "lasting cease-fire" in war-torn Libya, where a fragile truce has been in place since January.
The text, drafted by Britain, was approved by 14 votes out of 15, with Russia abstaining.
It was subject to weeks of wrangling, reflecting deep international divisions over Libya despite world leaders recently agreeing to end all foreign interference in the country and to uphold a weapons embargo.
The resolution affirmed, "the need for a lasting cease-fire in Libya at the earliest opportunity, without pre-conditions."
It also expressed "concern over the growing involvement of mercenaries in Libya."
Russia had pushed to replace the word "mercenaries" with "foreign terrorist fighters."
Libya, Africa's most oil-rich nation, has been mired in chaos since the 2011 NATO-backed uprising that toppled and killed longtime dictator Moammar Gadhafi.
Since April 2019, the U.N.-recognized Government of National Accord (GNA) has fought back against an offensive by military commander Khalifa Haftar, who is supported by Russia, Egypt and the United Arab Emirates.
A fragile cease-fire was established on Jan. 12 and at an international summit in Berlin a week later, world leaders agreed to end all foreign interference in Libya and to uphold a weapons embargo.
But there are still near-daily clashes near Tripoli and arms continue to flow into the country.
Moscow is accused of sending several thousand mercenaries from the private Russian security company Wagner to support Haftar, who controls much of the south and east of Libya. Russia, however, denies any involvement.
During negotiations, the U.S. demanded the Wagner group be clearly identified in the text, diplomats told AFP, before accepting the sole mention of "mercenaries."
The deputy U.S. ambassador to the U.N., Cherith Norman Chalet, lamented after the vote that the Council was not united.
"It's also very unfortunate that foreign mercenaries, including from the Kremlin-linked Wagner group, are making an inclusive political solution harder to achieve," she said.
Russia's U.N. ambassador, Vasily Nebenzia, said his country abstained because of doubts in Moscow about the possibility of enforcing the resolution when the warring parties had not yet agreed to the terms of the cease-fire.
The resolution called for continued negotiations by the joint military commission set up in January between the two sides, to achieve a "permanent cease-fire."
This would include a monitoring system, a separation of forces and confidence-building measures.
The commission's Geneva meeting ended Saturday without a resolution, but the U.N. proposed resuming talks as of Feb. 18.
The resolution also called on U.N. Secretary-General Antonio Guterres to submit proposals for monitoring the cease-fire "as soon as possible, when a cease-fire is agreed by the Libyan parties."
It also called on regional organizations – "notably the African Union, League of the Arab States and European Union" – to collaborate in order to "support the U.N." in its search for a political solution and supervision of a cease-fire.
More than 1,000 people have died in the clashes between Haftar and the GNA, while another 140,000 have been displaced, according to the U.N.
