BERLIN — World leaders were poised to commit to ending all foreign meddling in Libya's war at a Berlin summit Sunday, but calls were growing for an international force to ensure that pledges are put into action.

The presidents of Russia, Turkey and France were among global chiefs at the talks held under the auspices of the United Nations, which wants foreign powers wielding influence in the region to stop interfering in the war — be it through weapons, troops or financing.

France's President Emmanuel Macron on Sunday hit out against foreign troop deployments in war-ravaged Libya, saying such intervention only serves to fuel the conflict and create new risks for everyone.

Voicing his "acute concerns over the arrival of Syrian and foreign fighters in the city of Tripoli", Macron told a Berlin summit on Libya that "that must end".

Ankara has been accused of sending hundreds of Syrian fighters into Tripoli to back up Fayez Al-Sarraj's government while Moscow has allegedly deployed mercenaries to lend support to Khalifa Haftar.

Leaders of both warring factions — Haftar and Sarraj — were also in Berlin for the first such gathering since 2018.

Ahead of the talks, Turkish President Recep Tayyip Erdogan hit out at Haftar, saying he needed to drop his "hostile attitude" if Libya is to have any chance at winning peace.

If all goes to plan, all sides will sign up to a plan to refrain from interference, and commit to a truce that leads to a lasting end to hostilities, according to a draft of a final communique seen by AFP.

That document also urges all parties to re-commit to a much-violated UN arms embargo and raises the prospect of intra-Libyan political talks in Geneva at the end of the month.

But with warnings multiplying that pledges are often little respected in reality, calls have grown for international monitors to police the promises.

Clashes since April have killed more than 280 civilians and 2,000 fighters and displaced tens of thousands, until a fragile ceasefire backed by both Ankara and Moscow was put in place on Jan. 12.

EU's chief diplomat Josep Borrell too stressed that monitors must be present to check that any ceasefire and weapons embargo are respected.

With the idea gathering pace, British Prime Minister Boris Johnson said London would be ready to send "people and experts" to help monitor a Libya ceasefire.

Italian Prime Minister Giuseppe Conte likewise said his country "is ready to bring its contribution".

Johnson said Sunday that Britain would be ready to send "people and experts" to help monitor a Libya ceasefire should one be brokered by world powers at a summit in Berlin.

Johnson told Britain's Sky News television on his arrival in the German capital that it was time for "external proxies" to stop interfering in the war.

"Proxy conflicts only come to an end when the external proxies decide that they want to bring it to an end," said Johnson.

"We want to have a UN-led peace process and stop this jockeying for position. The people of Libya have suffered enough."

Asked whether UK forces could play a ceasefire monitoring role, Johnson replied: "If there is a ceasefire, yes of course there is a case for us doing what we do very well, which is sending people, experts to monitor the ceasefire. "I don't see any ceasefire at the moment," he added. "That's what we are arguing for today."

Russia also appeared open to the idea, with President Vladimir Putin's special representative Mikhail Bogdanov saying that the "idea must be discussed on the basis of consensus."

For Turkey, the fall of Sarraj's GNA could jeopardize a maritime boundary agreement the parties signed. It gives Ankara extensive rights over the eastern Mediterranean where the recent discovery of undersea gas reserves has triggered a scramble by littoral states.

Erdogan has repeatedly urged Europe to stand united behind Sarraj's government, warning that Tripoli's fall could allow militant groups like the Daesh (so-called IS) or Al-Qaeda to regroup.

He has also cautioned that further unrest could prompt a new wave of migrants to head for Europe.

Underlining the stakes involved, German Foreign Minister Heiko Maas said "we have to make sure Libya doesn't become a second Syria." — AFP
