"The Claw-Eagle Operation has started. Our planes are bringing the caves down on the terrorists' heads", the Turkish Ministry of National Defence tweeted on late Sunday.
According to TRT Haber, F-16 fighter jets from different provinces took part in the offensive.
The PKK/YPG seek to establish a Kurdish autonomous state, including in parts of Turkey, an aspiration that expectedly has met a strong confrontation in Ankara and prompted anti-PKK raids by the Turkish security forces. The Turkish military also attack Kurdish forces in northern Iraq and it was the fight against the Kurdish terrorists that Ankara said was the reason for its military operation in northern Syria.
