At least two civilians were killed and three others were injured in a car bomb attack in Syria's northwestern city of Azaz, Turkey's National Defense Ministry said on Monday.

"According to initial reports, a car bomb detonated by the terrorists outside the bus terminal in the centre of the city has killed 2 people and severely injured 3," the ministry said on Twitter.

It added that the YPG/PKK terrorists, "the enemy of humanity," targeted innocent civilians in Azaz.

Turkey on Oct. 9 launched Operation Peace Spring to eliminate terrorists from northern Syria, east of the Euphrates River in order to secure Turkey’s borders, aid in the safe return of Syrian refugees, and ensure Syria’s territorial integrity.

Ankara has reached two separate deals with the U.S. and Russia to pause the operation in order to allow YPG/PKK terrorists to withdraw from a planned safe zone, where Turkey wants to repatriate the refugees.

In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the U.S. and EU -- has been responsible for the deaths of 40,000 people, including women, children, and infants. The YPG is the PKK’s Syrian offshoot.
