CAIRO (Reuters) - U.S. forces said on Wednesday they killed 11 suspected militants in their second air strike in a week near the southern Libyan town of Murzuq, as the U.N. envoy warned of a growing risk of armed escalation and rights abuses in the country.
The strike comes as rival factions have been locked in a battle around the capital Tripoli, about 500 miles (800km) to the north, which forces loyal to eastern-based commander Khalifa Haftar have been trying to capture since April.
The U.S. attack, carried out on Tuesday deep in Libya’s southern desert, followed a Sept. 19 strike that the U.S. said had killed eight suspected militants.
“This air strike was conducted to eliminate ISIS (Islamic State) terrorists and deny them the ability to conduct attacks on the Libyan people,” Major General William Gayler, director of operations for U.S. Africa Command, said in a statement.
Some Islamic State militants retreated south into Libya’s desert as the group lost its stronghold in the coastal city of Sirte at the end of 2016.
The U.S., which has carried out occasional strikes in desert areas, has said it will not allow militants to use the fighting around Tripoli for cover.
The offensive on Tripoli by Haftar’s Libyan National Army (LNA) upended U.N.-led plans to broker a political settlement in Libya and soon stalled in the capital’s outskirts.
The conflict has spread outside Tripoli, with air and drone strikes against the port city of Misrata, Sirte, and Jufra in central Libya, U.N. Libya envoy Ghassan Salame told the U.N. Human Rights Council on Wednesday.
It had also triggered a “micro-conflict” in Murzuq, where more than 100 civilians are reported to have been killed over the past two months, he said.
“The conflict risks escalating to full-blown civil war,” Salame said by video link. “It is fanned by widespread violations of the U.N. arms embargo by all parties and external actors.”
“Serious violations of human rights and humanitarian law have been committed with total impunity, including increased summary executions, enforced disappearances, torture and ill-treatment as well as conflict-related sexual violence.”
Libya has been divided between rival factions based in Tripoli and the east since 2014, three years after a NATO-backed uprising ended Muammar Gaddafi’s four-decade rule.
Haftar’s LNA is battling forces aligned with the Government of National Accord (GNA), which was set up in 2016 following a U.N.-brokered deal.
Haftar’s foreign backers include the United Arab Emirates and Egypt, who diplomats and analysts say are vying for influence in the oil-rich nation with regional rivals Turkey and Qatar.
At least 128,000 people have been displaced by the fighting since April, according to U.N. estimates.
