Meanwhile, a Foreign Ministry official also rejected Russian media reports that the Turkish military operation along the Syrian border will be limited to Afrin.

Turkey has made no such commitment to Russia, the official was quoted by state-run Anadolu Agency as saying.

"Turkey's measures against the YPG cannot be limited to Afrin alone. There is also Manbij and east of the Euphrates River," Foreign Minister Mevlut Cavusoglu said in Vancouver, Canada last week.

Turkey on Saturday launched the operation dubbed as " Operation Olive Branch" with intense air raids and shelling seeking to oust from the Afrin region of northern Syria YPG, which Ankara considers a terror group affiliated to the Kurdistan Workers' Party (PKK).

It is Turkey's second major incursion into Syria after the August 2016 Euphrates Shield Operation in an area to the east of Afrin against both the YPG and Islamic State (IS) fighters.
