Libya’s UN-recognized Government of National Accord (GNA) claimed warlord Gen. Khalifa Haftar’s forces violated a cease-fire by targeting the town of Abu Grain on Saturday.

Haftar forces targeted the town that is 300 kilometers (168 miles) far from the capital of Tripoli, by warplane, said Mohammed Kanunu, military spokesman for the GNA in a statement.

No casualties were reported but it emphasized the attack came before the Berlin Conference, where the German leader invited sides in an attempt to achieve stability in the region.
