TRIPOLI/BENGHAZI — Eastern Libyan commander Khalifa Haftar ordered his troops on Thursday to march on the capital Tripoli, taking his conflict with the internationally recognized government to a dangerous new level.

UN Secretary-General Antonio Guterres, who is in Tripoli trying to push an international peace deal, called for restraint. When asked about Haftar’s statement, he said Libya needed a political not a military solution.

Haftar made his order in a video posted online hours after his forces took full control of Gharyan, a town about 100 km south of the capital.

“To our army which is stationed at the outskirts of Tripoli. Today we complete our march ... We are going to start shortly,” he said in the video titled ‘Operation to liberate Tripoli’.

The capture of Gharyan after skirmishes on Wednesday with forces allied to Tripoli-based Prime Minister Fayez El-Serraj followed a rapid thrust westward by Haftar’s Libyan National Army (LNA) from his eastern stronghold of Benghazi.

The developments mark a dramatic escalation of a power tussle that has dragged on in Libya since the overthrow of Muammar Gaddafi in 2011.

The country has been divided between the Western-backed government in Tripoli and a parallel administration allied to Haftar since Gaddafi’s downfall.

There was no immediate comment to Haftar’s statement from the government in Tripoli.

Earlier, after the news of the capture of Gharyan, it said it had put its forces on maximum alert, though it relies on armed groups with often flexible loyalty — several groups dumped the last government to support El-Serraj when he took power in 2016.

The developments are a setback for the United Nations and Western countries which have been trying to mediate between El-Serraj and Haftar, who met in Abu Dhabi last month to discuss a power-sharing deal.

A national conference is set to follow this month to agree on a road map for elections to resolve the prolonged instability in Libya, an oil producer and a hub for refugees and migrants trekking across the Sahara in the hope of reaching Europe.

Haftar’s forces control the east and recently expanded to southern Libya.

Their advance took diplomats and analysts by surprise while they were focused on neighboring Algeria, where President Abdelaziz Bouteflika resigned on Tuesday after weeks of protests.

Earlier on Thursday, one of Haftar’s commanders said his forces had taken full control of Gharyan. “Right now as we speak I’m driving through the town,” Abdelsalam Al-Hassi told Reuters by telephone.

Gharyan had been allied to the Tripoli government although some Haftar supporters were also based there.

The two sides fought skirmishes on Wednesday but these had ceased, town mayor Yousef Al-Bdairi said.

A town resident said: “The town now is under control of the army who came from the east and I can see their vehicles with their Libyan National Army logo.”

A group of armed groups in Misrata said they were ready to confront the LNA.

“All the leaders in the city demand El-Serraj to give orders to launch immediately an operation,” they said in a statement. — Reuters
