Libya’s renegade General Khalifa Haftar has left Moscow without signing an agreement that would have approved a tentative ceasefire in the leading North African oil exporter.

After hours of talks, Haftar on Monday requested until Tuesday morning to look over the agreement already signed by Fayez al Sarraj, the head of the United Nations-recognised Government of National Accord (GNA).

But the general, whose eastern-based forces launched an offensive to seize the GNA's base of Tripoli in April, left Moscow without signing the deal drafted at the indirect talks, Russia's Foreign Ministry said.
