At least three civilians were injured on Thursday in a missile attack carried out by the PKK terror group's Syrian branch, YPG, in northwestern Syria, according to local sources.

The terror group, attacking from Syria's Tal Rifaat, targeted the Maryamin region in western Afrin province.

Three civilians inside a vehicle were wounded in the attack. Those injured were taken to hospitals.

Afrin was largely cleared of YPG terrorists in 2018 through Turkey's anti-terror offensive Operation Olive Branch, but the terror group still has sleeper cells in the region.

The terror group often targets Jarablus, Azaz, Afrin and al-Bab by attacking from the adjacent Tal Rifaat and Manbij regions.

In its more than 40-year terror campaign against Turkey, the PKK – listed as a terror organization by Turkey, the U.S. and the EU – has been responsible for the deaths of nearly 40,000 people, including women, children and infants. The YPG is the PKK's Syrian offshoot.

Since 2016, Turkey has launched a trio of successful anti-terror operations across its border in northern Syria to prevent the formation of a terror corridor and to enable the peaceful settlement of residents: Euphrates Shield (2016), Olive Branch (2018), and Peace Spring (2019).
