TRIPOLI, Libya (UPDATED) – Fighting raged around Tripoli and an air strike closed its only functioning airport Monday, April 8, as Libyan strongman Khalifa Haftar defied international calls to halt his advance on the capital.
Thousands were also reported by the United Nations to be fleeing the capital city in face of Haftar's surprise assault which has left dozens dead.
The EU's foreign policy chief on Monday added her voice to those urging the eastern strongman to stop his offensive, in the wake of calls for restraint by the UN Security Council and the United States.
"I make a very strong appeal to Libyan leaders and in particular to Haftar to stop all military activities...and to return to the negotiation table," Federica Mogherini said after talks with EU foreign ministers.
Dozens of people have been killed and thousands displaced in the fighting since Haftar's forces launched their onslaught against Tripoli and its unity government on Thursday, April 4.
A security source at Mitiga airport, east of the capital, said no side had yet claimed responsibility for Monday's air raid, which hit a runway without causing casualties.
The civil aviation authority decided "to suspend aerial traffic until further notice" to the capital, said Mohammed Gniwa, a spokesman for national carrier Libyan Airlines.
An airport source, who did want to be named, confirmed the suspension.
The oil-rich northern African country has been rocked by violent power struggles between an array of armed groups since the NATO-backed overthrow of dictator Moamer Kadhafi in 2011.
Haftar, a former Kadhafi military chief, has emerged as a major player, his self-styled Libyan National Army backing an administration in the country's east in opposition to the UN-backed Government of National Accord.
Having seized control of much of eastern Libya and buoyed by a series of victories in the desert south, Haftar turned his sights on Tripoli, vowing to "cleanse" it of "terrorists and mercenaries."
After a pause overnight, fighting resumed Monday morning around the capital's destroyed main airport, some 30 kilometers (18 miles) south of Tripoli, and the rural area of Wadi Rabi further east.
World powers have expressed alarm at the violence, saying it threatens to further destabilize Libya and derail UN-led efforts to find a political solution to the country's woes.
The US has appealed for an "immediate halt" to combat operations and the UN Security Council has called on Haftar's forces to stop their advance.
On Sunday, April 7, Russia blocked proposals for the council to adopt a formal statement, instead insisting that all Libyan forces be urged to stop fighting, diplomats said.
Moscow is a key supporter of Haftar, along with Egypt and the United Arab Emirates.
But the Kremlin on Monday urged "all sides to reject actions that could provoke bloodshed in battle and the deaths of civilians."
Fierce clashes Sunday near Tripoli saw Haftar's fighters and other powerful western Libyan armed groups exchanging fire including air strikes.
Forces backing the Tripoli-based GNA on Sunday announced a counteroffensive dubbed "Volcano of Anger."
Spokesman Colonel Mohamed Gnounou said it was aimed at "purging all Libyan cities of aggressor and illegitimate forces," in reference to Haftar's fighters.
Civil war fears
Unity government health minister A'hmid Omar told Libya's Al-Ahrar television station late Sunday that around 50 people had been wounded along with those killed.
His ministry on Monday put the death toll at 35.
Haftar's forces have said 14 of their fighters have died.
The UN Humanitarian Coordinator in Libya, Maria Ribeiro, said Monday the fighting had displaced more than 2,800 people, blocked rescuers from reaching casualties and damaged electricity lines.
She again urged the warring parties to implement a temporary humanitarian ceasefire.
The previous day, fighting raged throughout a two-hour window set by the UN for a pause in hostilities for civilians and the wounded to flee.
Haftar's offensive has threatened to plunge the country into a full-blown civil war and once again thwart diplomatic efforts to find a solution to Libya's woes.
It was launched just days ahead of a planned UN conference aimed at uniting Libya's rivals and paving the way for elections.
Envoy Ghassan Salame has insisted the UN was "determined" to go ahead with the April 14-16 conference.
The UN mission in Libya said on Twitter that Salame met Monday with unity government head Fayez al-Sarraj in Tripoli to discuss how to "assist at this critical and difficult juncture." – Rappler.com
