Ankara views the PKK/PYD, which is the Syrian branch of the PKK, as a terrorist group and fears weapons supplied to the PKK/PYD for the operation to oust ISIS from Syria's Raqqah will end up in the hands of PKK terrorists fighting Turkish security forces.

More than 1,200 people, including security force personnel and civilians, have lost their lives since the PKK listed as a terrorist organization by Turkey, the U.S., and the EU -- resumed its decades-long armed campaign in July 2015.

Erdogan also vowed that Turkey would not tolerate a Kurdish state in northern Syria and said he supported the unity of both Iraq and Syria.

“Iraq will be a strong country as long as it protects its unity,” Erdogan added.

He also addressed the western countries' stance regarding the Fetullah terrorist Organization (FETO), an illegal network accused of orchestrating last year’s coup attempt in Turkey.

"Militants of the terror group who organized a deadly coup attempt on July 15 last year in my country and martyred 250 of my citizen and left 2,193 other wounded are seeing the Western countries as a safe harbor," he added.

According to the government, the coup on July 15, 2016, was organized by followers of U.S.-based Fetullah Gulen, who is accused of pursuing a long-running campaign to overthrow the government through supporters within the Turkish state, particularly the military, police and judiciary.
