Damascus:An alliance of Syrian Kurdish and Arab forces has managed to cut off the Daesh terror group’s main supply route to Turkey after encircling the Syrian border town of Manbij.

The Syrian Democrati Forces (SDF), a coalition of Kurdish, Arab, Assyrian, Armenian, and Turkmen fighters, backed by the People’s Protection Units (YPG), surrounded Manbij on Friday, said the so-called Syrian Observatory for Human Rights.

The SDF also blocked the road south of the town, which heads to Raqqah. The strategic city of Manbij, located in Syria’s Aleppo Province, is a key point along Daesh’s main supply line from the Turkish frontier to Raqqah.

Raqqa, on the northern bank of the Euphrates River, about 160 kilometers east of Aleppo, was overrun by Takfiri terrorists in March 2013, and in 2014 was proclaimed the center for most of the terrorists’ administrative and control tasks.

Syrian forces are now engaged in a military offensive to liberate the strategic town.

Daesh, however, still controls territory along the Turkish border with secondary roads to the frontier, but these are more dangerous and difficult to access, according to Observatory head Rami Abdel Rahman.

To “reach the Turkish border from Raqqah,” Daesh terrorists have to take a route that is more dangerous, because of the presence of Syrian troops and Russian air strikes, he added.

On Friday, the United Nations along with the Syrian Arab Red Crescent sent humanitarian aid supplies to the town of Daraya, near the capital Damascus, said UN spokesman Jens Laerke.
