Forces loyal to Libya’s internationally recognized government captured the last major stronghold of eastern commander Khalifa Haftar near Tripoli on Friday, capping the sudden collapse of his 14-month offensive on the capital. Military sources in Haftar’s Libyan National Army, LNA, said their forces had withdrawn from the town of Tarhouna. They headed toward Sirte, far along the coast, and the air base of Al-Jufra in central Libya. The LNA made no immediate official comment. The advance extends the control of the Government of National Accord, GNA, and allied forces across most of northwest Libya, reversing many of Haftar’s gains from last year when he raced toward Tripoli. The United Nations has started holding talks with both sides for a cease-fire deal in recent days, though previous truces have not stuck. The GNA gains could entrench the de facto partition of Libya into zones controlled by rival eastern and western governments whose foreign backers compete for regional sway. Turkish military support for the GNA, with drone strikes, air defenses and a supply of allied Syrian fighters, was key to its recent successes. Ankara regards Libya as crucial to defending its interests in the eastern Mediterranean. However, the LNA still retains its foreign support. Washington said last week Moscow had sent warplanes to LNA-held Jufra, though Russia and the LNA denied this. The United Nations says weapons and fighters have flooded into the country in defiance of an arms embargo, risking a deadlier escalation. Meanwhile, a blockade of oil ports by eastern-based forces has almost entirely cut off energy revenue and both administrations face a looming financial crisis. Stronghold Located in the hills southeast of Tripoli, Tarhouna had functioned as a forward base for Haftar’s assault on the capital. Its swift fall suggests Haftar’s foreign supporters were less willing to sustain his bid to take over the entire country once Turkey intervened decisively to stop him. The GNA operations room said in a statement that its forces had captured Tarhouna after entering from four sides. Abdelsalam Ahmed, a resident, said GNA forces had entered the town. Videos and photographs posted online appeared to show GNA forces inside Tarhouna cheering and hugging each other and firing into the air. “The Libyan government forces are rapidly moving in an organized manner and with armed drones. There could be a solution at the table, but Haftar’s forces are losing ground in every sense,” said a Turkish official.
