A State Department spokesperson said the US was aware of reports that four Javelin missiles were found at a base used by men under the command of Khalifa Haftar, a military leader who has waged a months-long offensive against Libya’s internationally recognised government based in Tripoli.
Markings indicate the missiles were first sold to the United Arab Emirates, a major buyer of US arms, according to a report published by The New York Times on Friday.
“We take all allegations of misuse of US origin defence articles very seriously. We are aware of these reports and are seeking additional information,” a State Department spokesperson said on condition of anonymity.
“We expect all recipients of US origin defence equipment to abide by their end-use obligations.”
The missiles were apparently discovered this week when forces loyal to the Government of National Accord (GNA) recaptured the strategic town of Gharyan in a surprise attack, seizing the main supply base for Haftar’s offensive.
In Tripoli, the GNA on Saturday showed journalists three Javelin missiles and seven Chinese-made Norinco GP6 artillery weapons it said had been seized from Haftar’s base.
“These are a sample that we have obtained permission to bring here,” GNA fighter Ibrahim al-Touil said, adding he could not disclose the total number of the weapons.
The New York Times reported that markings on the missiles indicated they had been sold to the UAE, a US ally, in 2008.
If they were then sold or transferred to Haftar, that would violate both the terms of the sale and a UN arms embargo on Libya, the report said.
The UAE, Egypt and Saudi Arabia are seen as key supporters of Haftar.
Chinese-made attack drones were also found, the newspaper reported.
The State Department official said Washington supports the efforts of UN special envoy to Libya Ghassan Salame “to help avoid further escalation and chart a path forward that provides security and prosperity for all Libyans.”
“We call on all parties to rapidly return to UN political mediation, the success of which depends upon a ceasefire in and around Tripoli,” the US official said.
Hundreds of people have been killed and tens of thousands displaced in the offensive on Tripoli, while diplomatic efforts to revive political talks have foundered.
Haftar on Saturday promised a “tough response” to the surprise attack and accused militias backing the Tripoli-based Government of National Accord of executing his wounded troops at the town’s hospital – allegations refuted by both the GNA and authorities in Gharyan.
Dozens of pro-Haftar fighters were killed in the clashes some 100 kilometres (60 miles) south of the capital, with at least 18 taken prisoner, a GNA spokesman said.
AFP correspondents who toured Gharyan were shown signs of a hasty retreat by Haftar’s forces, who left behind their wounded, a command post, arms, ammunition and even food burning on stoves.
“The speed (of the attack), the surprise element and the revolt (by the area’s residents) sowed fear” in the ranks of Haftar’s fighters, General Ahmad Bouchahma, a senior GNA officer, said during a tour of the area.
