At least 21 people were injured in two bomb attacks in Ras al-Ayn, northeastern Syria, local security sources said on Saturday.
The explosives detonated near the town post office, according to the sources, who asked not to be named due to restrictions on speaking to the media.
At least 21 people -- mostly children and women -- were injured in the attack and referred to the closest hospital.
Just after the blast, an explosives-laden motorbike exploded near the town's entrance, where no casualties were reported.
The local security forces are considering the possibility that the YPG/PKK terror group might be behind the attack near Turkey's southern border.
Ras al-Ayn was liberated from YPG/PKK terrorists last October as part of Turkey's Operation Peace Spring, launched to secure Turkey's borders by eliminating the terror group from northern Syria east of the Euphrates River, aid in the safe return of Syrian refugees, and ensure Syria's territorial integrity.
In its more than 30-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.
