An airstrike by the so-called US-led coalition purportedly targeting the Takfiri Daesh terrorist group in Syria has killed at least 20 civilians and injured 40 others in a countryside in the northwestern city of Aleppo.


The fatalities were caused after warplanes bombed the majority Kurdish village of Thulthana in the northern province of Aleppo around midnight Tuesday, the official SANA news agency reported.


The Britain-based so-called Syrian Observatory for Human Rights also said at least 19 civilians, including three children, were killed in the deadly attack.


Some media outlets said Turkey’s military, which is part of the coalition, had conducted airstrikes in the Syrian village, which is currently being held by Daesh.


In a statement on Wednesday, the general staff of the Turkish armed forces denied that civilians had been killed, saying, “The operation in the region is carried out extremely carefully, and airstrikes are carried out only after the selected targets have been confirmed several times.”


The United States has been leading an aerial bombardment campaign targeting alleged Daesh positions in Syria since 2014.


In early September, Turkish troops entered the Syrian territory in a sudden incursion, which resulted in the fall of Jarablus after Daesh left the city without resistance.


Turkey has sent troops deeper into the Syrian territory to establish what it calls a safe zone.


The Kurdish People’s Protection Units (YPG), a US-backed militant group in Syria, and its allied Democratic Union Party (PYD) have frequently condemned bombings by Turkey in mainly Kurdish areas, saying Turkish forces “are targeting innocent civilians under the pretext of combating terrorism.”


Ankara views the YPG and PYD as terrorists linked with the Kurdistan Workers’ Party (PKK), which has been fighting for autonomy in Turkey’s Kurdish-dominated regions for decades.
