This is the first time for Turkey to get engaged in such an attack.
Ankara has long championed robust backing for Syria's militants. It has maintained an open door policy, providing a lifeline to militant-held areas by allowing them to organize on its soil.
Earlier this month, Syrian President Bashar al-Assad echoed similar concerns in an interview with Turkey's Halk TV, warning that Ankara will pay the price for supporting militants, as they would eventually turn against their host.
"It is not possible to use terrorism as a card and put it in your pocket because it is like a scorpion which won't hesitate to sting you at any moment," Assad said, adding, "In the near future, these terrorists will have an impact on Turkey. And Turkey will pay very dearly for its contribution."
