LIBYA’S internationally recognized government Tuesday paused talks hosted by the United Nations (U.N.) to halt war over the capital after eastern forces shelled Tripoli’s port, almost hitting a highly explosive gas tanker and disrupting fuel supplies.

The U.N. has been hosting in Geneva cease-fire talks between officers from the Tripoli government and the eastern-based Libya National Army (LNA), which has been trying to take the capital in a near-yearlong campaign displacing at least 150,000 people.

The talks had been agreed to by foreign powers backing rival parties at a summit in Germany a month ago, an event that has not halted the war that has ripped apart the oil producer since the toppling of Muammar Gaddafi in 2011.

The LNA on Tuesday shelled Tripoli port, first saying it had attacked a Turkish vessel bringing weapons but saying later it had hit an arms depot. Heavy artillery fire could be also heard late at night in parts of Tripoli though details were unclear.

In response, the Tripoli-based Government of National Accord said in a statement it suspended its participation in cease-fire talks “until firm responses are taken against the attacker, and we will respond firmly to the attack in appropriate timing.”

“Negotiations don’t mean anything without permanent cease-fire guarantees returning the displaced people and the security of the capital and the other cities,” it added.

Tripoli port is a major gateway for food, fuel, wheat and other imports for the capital, which is home to the internationally recognized government.

State oil firm NOC said it had urgently evacuated all fuel tankers from the port after a missile struck meters away “from a highly explosive liquefied petroleum gas (LPG) tanker discharging in the port.”

“Today’s attack on Tripoli port could have led to a humanitarian and environmental disaster,” NOC Chairman Mustafa Sanalla said.

“The city does not have operational fuel storage facilities. ... The consequences will be immediate; hospitals, schools, power stations and other vital services will be disrupted,” he said.

Tripoli-based forces said the LNA had fired four missiles.

Since January, Turkey has sent several ships carrying arms and heavy trucks to Tripoli and Misrata, another western port allied with the Tripoli government, diplomats said.

The LNA is allied with a parallel government in eastern Libya supported by the United Arab Emirates, Egypt, Jordan and Russian mercenaries. Eastern ports and airports are out of range of the Tripoli forces and its Turkish drones.

Tuesday’s attack on the port unfolded as officers from the Tripoli forces and the LNA held a second round of indirect talks in Geneva to establish a permanent cease-fire. Both sides refused again to sit in the same room, U.N. Libya envoy Ghassan Salame said, though he said he was hopeful of making progress. (SD-CGTN)
