Khalifa Haftar’s Libyan National Army spokesman Ahmed Mismari said that the armed forces had taken full control of Tripoli international airport and had advanced into the capital’s southern outskirts.

The offensive by the LNA, which is allied to a parallel administration based in the main eastern city of Benghazi, intensifies a power struggle that has fractured the oil-producing country since the 2011 overthrow of Muammar Gaddafi.

G7 foreign ministers warned eastern Libyan Military Commander Haftar to halt his thrust on Tripoli, menacing the internationally recognized government based there, or face possible international action.

The United Nations is scheduled to hold Libya’s national conference on possible elections on April 14, with aims to reach agreement on a road map for elections to resolve the protracted instability in the country.
