Senior US officials met with Libyan strongman Khalifa Haftar Monday to discuss steps toward ending his offensive on Tripoli, and accused Russia of exploiting the conflict, the State Department said.

The delegation, which included the US ambassador to Libya Richard Norland, aimed to establish “steps to achieve a suspension of hostilities and a political resolution to the Libyan conflict,” the statement read.

The officials underscored full US “support for the sovereignty and territorial integrity of Libya and expressed serious concern over Russia’s exploitation of the conflict at the expense of the Libyan people.”
