According to the so-called UK-based Syrian Observatory for Human Rights, the airstrikes on Friday targeted a Daesh hideout in the town of Hajin, located along the Euphrates River, south of Deir ez-Zor.
At least 26 people, including 14 kids, were killed during the raids, the report added.
The coalition’s raids earlier killed another seven civilians in the nearby village of al-Shaafa on Thursday, Observatory chief Rami Abdel Rahman said.
Hajin’s civilians were also targeted by the airstrikes of the coalition’s fighter jets last Saturday, when 15 people, mostly women and children, were killed.
The US-led coalition has been conducting airstrikes against what are said to be Daesh targets inside Syria since September 2014 without any authorization from the Damascus government or a UN mandate.
The military alliance has repeatedly been accused of targeting and killing civilians. It has also been largely incapable of achieving its declared goal of destroying Daesh.
On December 14, 2017, Syria’s Ministry of Foreign Affairs and Expatriates stated that the US-led coalition was indeed targeting civilian facilities and providing Daesh terrorists with cover.
