Germany’s foreign minister headed to Libya on Thursday to persuade Libyan General Khalifa Haftar to join an international conference on the conflict, as the UN urged support for the peace initiative.

Axar.az reports citing foreign media that Heiko Maas said the Berlin conference – scheduled for Sunday – was “the best chance in a long time” for peace talks in Libya, which has been in chaos since the 2011 uprising that killed former Libyan President Muammar Qaddafi.

Maas was due to meet Haftar in the eastern city of Benghazi – one of the general’s strongholds – days after meeting his rival Fayez al-Sarraj, who serves as head of the UN-recognized Government of National Accord (GNA) in Tripoli.
