At least four YPG/PKK terrorists were killed on Wednesday in east of Euphrates River, northern Syria, according to security sources.
The Turkish howitzers fired artillery shells on terror positions in Ayn al-Arab region in a cross-border shooting from Şanlıurfa, a border province in southeastern Turkey, said the sources who spoke anonymously due to restrictions on speaking to the media.
Six terrorists were also injured, the sources added.
In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the U.S. and the EU -- has been responsible for the deaths of some 40,000 people, including women and children.
