BRUSSELS, May 10 (Xinhua) -- NATO Secretary General Jens Stoltenberg is scheduled to meet the Head of the United Nations Support Mission in Libya Ghassan Salame at NATO Headquarters Monday, the North Atlantic Treaty Organization said Friday in a statement.

During his visit to NATO, Salame will also attend a meeting of the North Atlantic Council, the statement said.

Salame is currently in a tour to European capitals to discuss ways to immediately stop the fighting and resume a political dialogue in Libya.

Conflict broke out in Libya over a month ago when forces loyal to Khalifa Haftar, commander of the Libyan National Army, attacked Tripoli, seat of the internationally-recognized Government of National Accord.

Since April, eastern-based Libyan forces led by Haftar have been advancing in a push to seize Tripoli but troops loyal to Prime Minister Fayez Al-Serraj's internationally-recognized government have so far kept them at bay.

According to the World Health Organization, more than 400 people were killed and at least 2,000 wounded since early April, with 11 additional ambulances have been impacted or suffered collateral damage.

Since the ouster and killing of former Libyan leader Muammar Gaddafi in 2011, Libyan factions have been engaged in a civil war that escalated in 2014, resulting in splitting power between two rival governments in the northwestern city of Tripoli and the northeastern city of Tobruk respectively.
