WASHINGTON (Sputnik) — The US envoy and Turkish officials also reviewed the progress of the Euphrates Shield operation inside Syria, the release added.
On August 24, Turkish forces, backed by US-led coalition aircraft, began a military operation dubbed the Euphrates Shield to clear the Syrian border town of Jarabulus and the surrounding area of the Islamic State terrorist group.
When Jarabulus was retaken, the joint forces of Turkey, the coalition and Syrian rebels continued the offensive southwest.
The operation has been widely criticized both by the Syrian Kurds and Damascus, who have accused Ankara of violating Syria's territorial integrity.
