BELGRADE – Turkish forces and Syrian rebels expelled the Islamic State (ISIS / Daesh / ISIL / IS) terrorist group from the last areas of the Syrian-Turkish border under their control on Sunday, the Syrian Observatory for Human Rights said.

“IS [Daesh / ISIS / ISIL] has lost its contact with the outside world after losing the remaining border villages between the Sajur River … and Al-Rai,” the Britain-based monitor said.

Turkey has sent more tanks into the northern Syrian village of al-Rai from Kilis province to support Syrian rebels fight Islamic State, Turkish media reported.

At least 20 tanks, five armored personnel carriers, trucks and other armored vehicles crossed the border, marking Turkey’s second incursion since it launched the so-called “Euphrates Shield” operation along with Free Syrian Army units on August 24.

Since then, rebels have been seizing villages along the Turkish border near Jarablus and the western Cobanbey district from IS, the reports said.

The Turkey-backed Free Syrian Army units have also been fighting U.S.-backed Kurdish People’s Protection Units (YPG).

Meanwhile, Turkish President Recep Tayyip Erdogan said Saturday that terrorism is a long-term issue for discussion by members of the Group of 20 nations gathering in China’s Hangzhou coastal city for their 2016 summit.
