Large contingents of Syrian Turkman rebel militias are being transferred to Libya by Turkish airlift and sealift to help the Tripoli government repel the assault on the capital by Gen. Khalifa Haftar’s Libyan National Army, DEBKAfile’s military sources report. The LNA has just broken through the government’s defense lines and is driving toward the center of Tripoli. Haftar is backed by Russia, Egypt and the UAE. Sources in Syria and Turkey disclose that the rebel Syrian units heading for Libya are the Sultan Murad Brigade and the Faylaq al-Sham, most of whose fighters belong to the Syrian Muslim Brotherhood. This is the first time that combatants from Syria’s civil war are participating in the conflict of a fellow Arab nation.
