Libya's rival authorities have announced an immediate ceasefire.
The Tripoli-based and internationally recognised Government of National Accord (GNA) published a statement that also calls for elections in March next year.
The truce was also agreed by an ally of Gen Khalifa Haftar, who controls large parts of the east and south of Libya.
Libya has been riven by violence since Col Muammar Gaddafi was deposed by Nato-backed forces in 2011.

Both the UN and Egypt's President Abdul Fattah al-Sisi, who also backs Gen Haftar, have welcomed the agreement.

France is also thought to back Gen Haftar, although leaders in Paris have repeatedly denied this.
A UN arms embargo is in place to stop men and materiel flowing into the country, but it has had little effect.
Turkey agreed a military co-operation deal with the GNA in 2019, and deployed troops to the country in January.
