"The presence of the Turkish Army in Syria is unacceptable and a sign of aggression. We will fight, by all means, against them as invaders," the statement said.
Earlier, the representatives of Kurdish militants in Syria accused the Turkish Army of helping extremists and targeting Kurds' positions, including, most recently, sending 20 tanks to cover extremists' offensive on the city of Tel Rifaat in Aleppo province.
On August 24, Turkish forces, backed by US-led coalition aircraft, began a military operation also called Euphrates Shield to clear the Syrian border town of Jarabulus and the surrounding area of Daesh, outlawed in Russia and many other countries. As Jarabulus was retaken, the joint forces of Ankara, the coalition and Syrian rebels continued the offensive southwest.
