An Arab-Kurd opposition alliance backed by the coalition on Friday (June 10th) severed a key supply route of the "Islamic State of Iraq and the Levant" (ISIL) in northern Syria, AFP reported.
The Syrian Democratic Forces (SDF) cut off the last road from Manbij to the Turkish border, according to the Syrian Observatory for Human Rights.
Manbij lies at the heart of the last stretch of territory along Turkey's border still under ISIL control, and was a key point on its supply line.
Other secondary roads to the frontier are more dangerous and difficult to access, Observatory head Rami Abdel Rahman said.
This week the SDF, backed by coalition airstrikes, cut the road north out of Manbij to the ISIL-held border town of Jarablus, which the group had used as a transit point for fighters, money and weapons. The SDF also blocked the road south out of Manbij heading to al-Raqa.
