The US coalition launched airstrikes on the town of Souseh, which is located in the last pocket held by Islamic State (IS) militants in the eastern countryside of Deir al-Zour, according to the Syrian Observatory for Human Rights.
Women and children were among the killed in the aerial bombardment, reported Xinhua news agency quoting the London-based watchdog.
The US-led coalition is supporting the Kurdish-led Syrian Democratic Forces in their advance on the IS-held areas on the eastern bank of the Euphrates River in eastern Deir al-Zour.
The Syrian Foreign Ministry recently urged the UN to conduct an international investigation into the “crimes” of the US-led coalition in Syria, charging that Washington is using the anti-IS battles as a pretext for continued intervention in Syria’s affairs.
The US-led coalition entered the course of anti-IS battles in Syria in 2014 without the consent of the Syrian government, which questions its intention and brands its intervention as illegal.
