ANKARA, August 22 /TASS/. Turkey is calling on Iran, Russia and the United States to open "a new chapter" in the Syrian settlement, Turkish Prime Minister Binali Yildirim said on Monday.

"It is vitally important for Turkey, Iran, Russia and the United States to open a new chapter in Syria without marking time," Turkey’s T24 quoted Yildirim as saying.

The Turkish prime minister also described as unacceptable the creation of a Kurdish state entity in northern Syria.
