Has Khalifa Haftar's campaign in Libya failed?

Renegade military commander loses last stronghold in western Libya following similar defeats.

Renegade military commander Khalifa Haftar's ambitions in Libya are unravelling quickly.

The 76-year-old launched an offensive 14 months ago to capture the capital, Tripoli, from the United Nations-recognised Government of National Accord (GNA).

The GNA's forces say they have regained full control of Tripoli and pushed Haftar's fighters from Tarhuna, their last stronghold in western Libya.

This follows weeks of similar defeats and losses of territory for Haftar's forces along the coast.

What role will Turkey play in Libya?

Turkey says it will increase its military support to the internationally recognised government of Libya if necessary.

Turkey is considering all kinds of military backing for Libya. That includes ground, marine and air support, if necessary.

President Recep Tayyip Erdogan also said he is ready to deploy troops if the internationally recognised government of Libya formally requests help.

The Government of National Accord, or GNA, has been fighting an offensive by rebel forces to unseat Prime Minister Fayez al-Sarraj since April.

Renegade military commander Khalifa Haftar announced his final push to seize the capital Tripoli earlier this month.

His forces extended to Wednesday a deadline for pro-government forces to withdraw.
