Advances made by autonomy-seeking Syrian Kurds, led by the Democratic Union Party (PYD), have irritated Ankara, which sees their plans as a threat to Turkey's national security and says it could stoke separatism among Turkish Kurds.
Earlier, Turkish fighter jets attacked the Syrian Kurds' armed People's Protection Units (YPG) several times after they defied Ankara's orders not to cross the Euphrates River's western area. The YPG fighters and their Kurdish Peshmerga allies in northern Iraq have played a key role in fighting ISIL.
Erdogan's approach to the Kurds is a disaster for Syria, Turkey, and, of course, the Kurds. https://t.co/yoAwbfY1r9

In light of its failure to find partners in Syria to fight ISIL, Al Nusra and other terrorist organizations, the US has sought to work together with the YPG. Retired General John Allen testified before Washington's Senate Foreign Relations Committee on US Mideast strategy, where he said the US was in a "very delicate, diplomatic process" in trying to work with Turkey and the YPG at the same time. Turkey's Kurdistan Workers Party (PKK), which is affiliated with the PYD, remains designated as a terrorist group by the US State Department.
However, Erdogan blamed the PYD for conducting "ethnic cleansing" in the area, saying that Western support for the Syrian Kurdish militias is tantamount to backing terrorism.
"The PYD is committing ethnic cleansing here [of] Arabs and Turkmen. If the Kurds withdraw and don't form a canton, there's no problem. But if the mindset continues, then what is necessary will be done or we face serious problems," Erdogan said.
He also said that Turkey is "determined to fight anything that threatens us along the Syrian border, inside or out."
His remarks came as Turkey launched a two-front military campaign against the Islamic State group in Syria and the Kurdistan Workers' Party (PKK) in northern Iraq.
The Suruc suicide bomber was reportedly affiliated with ISIL. The PKK claimed responsibility for the Ceylanpinar killings, saying that the policemen had backed the Islamic State group.
