Beirut: Air strikes by the US-led coalition fighting the Daesh group killed 20 civilians in Syria’s eastern Deir Al Zor province, a monitor said on Tuesday.
The Syrian Observatory for Human Rights said the deaths came in two separate incidents on Monday.
It also reported 10 civilians, among them nine children, were killed in a suspected Russian air strike on Tuesday on a town in the rebel-controlled province of Idlib.
The Observatory, which relies on a network of sources inside Syria for its information, says it determines whose planes carry out raids according to type, location, flight patterns and munitions used.
The Britain-based monitor said a US strike on Monday night on the Deir Al Zor town of Albu Kamal had killed 13 civilians, among them five children.
The strike also killed three members of Daesh, which controls the town by the Syria-Iraq border, the monitor said.
Earlier Monday, a US-led coalition strike killed seven civilians, including a child, in the village of Hussainyeh, the monitor said.
The US-led coalition has been carrying out air strikes against Daesh in Syria since 2014 and is providing air support for a Kurdish-Arab alliance advancing on the Daesh bastion of Raqqa.
Last month, the coalition said its campaign against Daesh in Syria and Iraq had unintentionally killed at least 220 civilians, but monitors say the real number is far higher.
Most of the oil-rich province of Deir Al Zor, in Syria’s east, is held by Daesh, including parts of the provincial capital, Deir Al Zor city.
The militants have besieged the remaining government-held parts of Deir Al Zor city, trapping civilians inside with limited access to supplies.
More than 320,000 people have been killed in Syria since the conflict began with anti-government protests in March 2011.
