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