The Turkish military retaliated against attacks of the PYD/PKK terror group from Syria's Afrin on Jan. 19-20, destroying shelters and hideouts, a military statement said.
The statement by Turkey's General Staff said the army hit the terrorist group's shelters within the scope of legitimate self-defence.
Turkish military units are already deployed in Afrin, a district of Aleppo under siege by the PYD/PKK terrorist organization located near the Turkey-Syria border.
The PYD/PKK is the Syrian offshoot of the PKK, which is listed as a terrorist organization by Turkey, the U.S., and EU.
A likely military operation in Afrin would follow Turkey's successful seven-month Operation Euphrates Shield, which ended in March 2017.
