The agreement between Ankara and Moscow stipulates that Russia will "facilitate the withdrawal" of YPG elements and their weapons from an area that extends to a depth of 30 kilometers from the border with Turkey.
Erdogan said in a televised speech from Istanbul, "If the terrorists are not cleared (from the region), according to the agreed deadline, we will take control and cleanse ourselves," according to "Agence France Presse."
The Turkish president refers to the Kurdish People's Protection Units (YPG), the backbone of the Syrian Democratic Forces fighting the Islamic State terrorist organization.
Nonetheless, Erdogan stressed that Ankara had "largely achieved" its goal of establishing a "safe area", which it says protected its territory from Kurdish fighters and opened a safe passage for ISIS forces.
"If the projects we develop for between one and two million refugees are not supported in the first phase of their return, we will have no choice but to open our doors and let them go to Europe," Erdogan said.
Earlier this month, Turkey and the United States reached an agreement on the withdrawal of the Kurdish People's Protection Units (YPG) from an area of 120 kilometers between Tel Abyad and Ras al-Ain.
The agreement followed a Turkish military operation launched on 9 October 2019, during which Syrian armed factions loyal to Ankara fought against Kurdish forces, and human rights organizations said they had witnessed war crimes against civilians, in which dozens were killed.
