Two platoons of the Tarhouna militia moved in overnight because of an ongoing dispute with the national government, sparked by the disappearance of a militia leader on the airport road Sunday, the source said. The Libyan government sent emissaries to meet with the militia group Sunday night, Deputy Foreign Minister Abdul Karim Ahmed Bazama said. The talks were continuing Monday. The deputy foreign minister said he did not know where the militia leader was or the circumstances of his disappearance. At the airport, local journalists who have worked with CNN in the past said armed militia members escorted passengers to cars and described it as an evacuation of the terminal. It was unclear whether flights had been canceled. CNN's Jomana Karadsheh contributed to this report.
