At least one civilian was killed and two others were injured in a car bombing in northwestern Syria on Sunday, according to local sources.
The explosive-laden vehicle detonated in al-Bab district, which was cleared of terrorists with Turkey's Operation Euphrates Shield in 2017.
Security forces are evaluating the possibility that the YPG/PKK terror group might be responsible for the attack, the sources said.
In its more than 35-year terror campaign against Turkey, the PKK-listed as a terrorist organization by Turkey, the US, and 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.
