Turkey and Russia, which back opposing sides in Libya’s civil war, are working on a lasting ceasefire for the leading North African oil producer despite the postponement of talks on Sunday.

The conflict has forced Libya to suspend all oil exports, which provide the bulk of government revenues, leading to economic hardship.

Presidents of Turkey and Russia have "agreed to continue working together to establish a lasting ceasefire in Libya," Turkish Foreign Minister Mevlut Cavusoglu said.
