Damascus:Nearly 40 civilians, including children, have been killed in northeastern Syria in a series of airstrikes carried out by the US-led coalition “fighting” Daesh terrorists.

The London-based Syrian Observatory for Human Rights said on Thursday that US air assaults have claimed 38 lives in Syria’s Hasakah Province since Tuesday.

According to the report, 15 of the victims lost their lives when the air raids targeted a bakery in the city of al-Shadadi in Hasakah near the Iraqi border.

The aerial attacks against three Hasakah villages also killed 15 others, including three children, on Thursday, while eight more civilians died in similar raids elsewhere in the province.

US Lieutenant General Charles Brown, head of US Air Forces Central Command, said he was aware of reports of civilian casualties, adding the US-led coalition will begin assessing their credibility and start an investigation if required.

“I do know that we’ve been striking at that area over the past several days,” Brown said.

The UK-based monitoring group said 35 members of the Takfiri Daesh terrorist group were killed in separate air raids near the town of al-Houl, near the Iraqi border, and farther south.

The civilian casualties came after a warplane hit a hospital run by Doctors Without Borders, known by its French acronym MSF, in the northern province of Idlib on Monday, killing at least 25 people.

The Paris-based medical aid group has slammed the attack on its facility as “deliberate,” and called for an independent investigation into the killing.

Damascus says “intelligence information” showed US warplanes carried out the attack, but Washington has denied any involvement.

What is the US doing in Syria?

The US and a number of its allies have been conducting air raids against what they claim to be Daesh positions inside Syria since September 2014 without any authorization from Damascus or a UN mandate.

The coalition has repeatedly been accused of targeting and killing civilians and destroying Syria’s infrastructure.
