At least two children were killed in a mine blast in northern Syria on Sunday, according to Turkey's National Defense Ministry, EDNews.net reports citing Yeni Safak.

“The PKK/YPG terrorist organization once again showed its treacherous face.

“2 innocent children lost their lives as a result of the explosion of a mine laid by terrorists on the road used by civilians in Hafiyah village of Tal Abyad,” the ministry said on Twitter.

Tal Abyad was cleared of terrorists last October during Turkey's Operation Peace Spring, which was launched to eliminate YPG/PKK terrorists in the region east of the Euphrates River to secure Turkey’s borders, aid in the safe return of Syrian refugees and ensure Syria’s territorial integrity.

Since then, Turkey has reached agreements with both the US and Russia to force the terrorist group to withdraw from the planned terror-free zone.

However, the YPG/PKK has continued to carry out attacks in Tal Abyad and Ras al-Ayn districts despite pulling out of areas under a deal reached by Turkey and the US on Oct. 17.

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