The UN’s special envoy for Libya said Tuesday he had tendered his resignation, saying the world body could not successfully support the country’s political transition as its leaders had put their own interests above finding a solution.

“I tendered my resignation to the Secretary General,” Senegalese diplomat Abdoulaye Bathily told reporters after a Security Council meeting where he painted a sombre picture of the situation in the North African country, riven by conflict and civil war for over a decade.

Bathily’s resignation was accepted by Secretary-General Antonio Guterres, the UN chief’s office said.

The UN support mission in Libya (UNSMIL) “made a lot of efforts under my leadership over the last 18 months,” but the situation has deteriorated, Bathily said, condemning a “lack of political will and good faith” by Libyan leaders.

He called the situation “sad” as “the bulk of the Libyan population want to get out of this mess.”

“Under the circumstances, there is no way the UN can operate successfully,” he concluded. “There is no room for a solution in the future.”

Bathily also announced the delay of a national reconciliation conference, originally scheduled for April 28. A new date has not been set.

Libya is still struggling to recover from years of war and chaos after the 2011 overthrow of long time dictator Muammar Gaddafi. Although relative calm has returned to the oil-rich country in the past four years, clashes periodically occur between its myriad armed groups.
