At least 10 civilians were killed on Monday by a US-led airstrike on the country's northern province of al-Raqqah, the de facto capital of the Islamic State (IS) group, state news agency SANA reported.
The airstrike targeted a cotton mill in the village of Salhiyeh in the northern countryside of al-Raqqah, killing three workers and a displaced family of six as well as another person from the village.
Children were among those killed, SANA said, noting that the killing is another massacre by the US-led anti-terror coalition.
SANA said huge property losses were caused by the airstrike.
Last month, SANA said the US coalition carried out two "massacres" in the countryside of the northern province of Aleppo, killing tens of people.
In July, the coalition airstrikes on the countryside of Aleppo killed 165 civilians and wounded tens of others, SANA added.
The US coalition has been striking the IS positions in al-Raqqah, the main bastion of the group, and other IS-held areas in Aleppo since late 2014.
The US administration had previously admitted the falling of civilian victims in the course of striking IS-held territory in Syria.
