Turkey’s military intervention in Libya, involving the deployment of Syrian fighters, is the latest chess move in a long-running civil war that followed the 2011 revolution, the NATO-led intervention, and the overthrow of the dictator Muammar Qaddafi.

Libya’s civil war threatens to spill over into the already-restive Sahel and Lake Chad regions after becoming a “playground” for foreign forces in North Africa, UN Secretary-General Antonio Guterres said on Thursday.

Libya’s oil output will collapse “within days” to the lowest level since the 2011 civil war as a blockade of its export terminals has forced a rapid shutdown of production and electricity blackouts in parts of the country, according to the head of the national oil company.

The Head of the High Council of State (HCS) Khalid Al-Mishri said if the military developments continue to be negative such as shelling airports and civilian targets, the HCS won’t take part in Geneva dialogue.

The Government of National Accord announced Thursday resumption of flights at Tripoli’s Mitiga Airport and tasked the Transportation Ministry with taking the needed measures in this regard.

Algeria hosted a meeting with Libya’s neighbouring countries, including Egypt and Tunisia in an attempt to end the crisis in the country, even as Fayez Al-Sarraj says he does not have a “real partner” in brokering peace in Libya as neither he nor Khalifa Haftar met at the Berlin conference.

Turkish President Recep Tayyip Erdogan said in early January that Turkish troops were already on their way to Libya to support the internationally recognised Government of National Accord at its request. He, however, clarified on Monday that there were only military advisers on the ground.

A report issued by the Office of the Secretary-General of the United Nations, Antonio Guterres, revealed on Tuesday that the army of eastern Libya, led by Field Marshall Khalifa Haftar, carried out 850 airstrikes with drones, in addition to 170 jet strikes, including 60 precision-guided raids by foreign fighter aircrafts.

The only functioning airport in Libya‘s capital was shuttered on Wednesday after coming under attack despite a truce that world powers have pushed warring parties to respect.

On Monday, Turkish President Recep Tayyip Erdogan said as quoted by the country’s media that Ankara hadn’t sent any Turkish troops in Libya yet but only military advisers.
