Forces loyal to the Libyan National Army (LNA), commanded by Khalifa Haftar, have been ordered to advance to western Libya to combat terrorists. A video released by the LNA media office showed a convoy of armored vehicles and pickup trucks mounted with heavy guns on the road. “In fulfilment of his (Haftar) orders, several military units moved to the western region to purge the remaining terrorist groups located in their last hideouts,” the LNA said in a statement with the video. It gave no details but the area appears to be the coastal road linking the eastern city of Benghazi, the LNA main base, with Tripoli in western Libya. A resident in Ras Lanuf, an oil town located on the coastal road, said tanks and military convoys were seen heading westwards in the direction of Sirte. Sirte is in central Libya controlled by a force from the western city of Mistrata allied to the Tripoli administration. The United Nations is holding a conference this month in the southwestern city of Ghadames to discuss a political solution to prepare the country for elections and address security. UN Secretary-General Antonio Guterres meanwhile, arrived in Libya from Egypt later on Wednesday. "I have just arrived in Libya, totally committed to support a Libyan-led political process leading to peace, stability, democracy and prosperity for the Libyan people," he said on Twitter. Prior to his arrival, he stated he hopes that a meeting between Haftar and Government of National Accord head Fayez al-Sarraj in Abu Dhabi earlier this year would be an important step to guarantee unifying Libyas institutions. "We hope that the conversations that took place between Sarraj and Haftar in Abu Dhabi and the understanding will be an important step to guarantee that, and that this can be consolidated by a national conference."
