Erdogan said Turkey sent troops to conflict zones when requested, but did not receive support in return.
Turkey views the YPG as an extension of the Kurdistan Workers' Party (PKK), which is deemed a terrorist group by the USA, the European Union and Turkey.
Turkish President Recep Tayyip Erdogan has made the nationalist "grey wolf" sign during a Justice and Development party rally in the southern province of Mersin, reports said.
Erdogan asked. "We came in response to the calls on Afghanistan, Somalia and the Balkans, and now I am making the call, let's go to Syria". NATO, Turkey is not a NATO country?
Erdogan said that the ongoing operation is not to "occupy" the region but to liberate it from YPG/PKK and Daesh terrorists, and then hand it over to the people living there.
Under NATO charter, an attack on one of the alliance's members is an attack on them all.
Turkey's leader has scorched North Atlantic Treaty Organisation allies over their failure to support his "counter-terrorist" operation in the Kurdish-held Syrian region of Afrin, but expressed gratitude that they at least had no guts to openly oppose Ankara.
Airstrikes on PKK targets in northern Iraq, where the terrorist organization has its main base in the Qandil Mountain region, near the Iranian border, have been carried out regularly since July 2015, when the PKK resumed its armed terror campaign.
"In fact, they would openly oppose Turkey in Syria if they could".
According to the Turkish General Staff, the operation aims to establish security and stability along Turkey's borders and the region as well as protect Syrians from the oppression and cruelty of terrorists. The document, however, only stated that the ceasefire did not apply to such groups as Islamic State (IS, formerly ISIL/ISIS), Al-Qaeda and Al-Nusra front, and did not describe any Kurdish militias as terrorists.
