"Do you believe that YPG/PYD in Syria is working for the benefit and future of our Kurdish brothers?" Erdoğan asked. "Never. This is not the case."
He said he always spoke out against the abuse of Kurdish people's rights by Bashar al-Assad's regime.
"I asked him, back in the days when we were on good terms, why they did not give them [Kurds] identity cards or passports. But Assad never cared about them."
"DAESH EQUALS YPG/PYD IN SYRIA"
Erdoğan said that Daesh in Syria equaled "YPG/PYD".
"Whoever established Daesh and armed them, and wreaked carnage in the country [Syria], is now arming and controlling and guiding YPG/PYD," he said, in an indirect reference to the U.S.
For the Syrian people, their "only friend" is Turkey, he added.
"Our nation must know that enemies of Turkey and their local collaborators will never succeed to get what they aim at," he concluded.
Last Tuesday, Turkey's National Security Council termed the PKK/PYD terror group's ethnic cleansing in Syria "unacceptable".
The council met under the leadership of Erdoğan in capital Ankara.
"PKK/PYD/YPG terrorist organization's efforts to carry out a covert ethnic cleansing by changing the demographic structure of Syria is against international law and human rights, and, therefore, it is unacceptable," said a statement released after the meeting.
Turkey will continue to take every necessary measure at the Turkey-Syria border area to ensure its own security, the council said.
The PKK/PYD is the Syrian branch of the PKK terrorist network, which has waged war against Turkey for more than 30 years. Turkey considers PKK, PYD, and YPG all one and the same.
While recognizing the PKK as a terrorist group, the U.S. has treated the PKK/PYD/YPG as an ally in its anti-Daesh efforts, despite its PKK ties documented by Turkey.
Since the PKK launched its terror campaign in Turkey in 1984, tens of thousands of people have been killed.
