The European Union Foreign Policy Chief Federica Mogherini has urged the rival factions in Libya for political negotiations.
Chairing EU foreign ministers meeting in Luxembourg, she said further military action should be avoided, calling for implementation of truce.
Civil war in Libya has intensified since the overthrow of Muammar Gaddafi in 2011.
Khalifa Haftar’s Libyan National Army (LNA) is threatening the internationally recognized government based in capital.
The LNA moved into Tripoli’s southern outskirts and took over the former international airport.
Mogherini said EU ministers were united on echoing the G7’s call for eastern Libyan military commander Khalifa Haftar to halt his advance on Tripoli.
She said, return to political negotiations could stop the intensified fighting.
Power struggle has fractured the oil-producing country.
