At least 14 Syrian civilians have been killed and 30 more injured in a US airstrike in the city of Dayr al-Zawr.
According to Syrian new sources on Monday, the strike was launched on the government-held region of Qusur.
"Fourteen civilians were killed and more than 30 others injured in air strikes by coalition planes on the Al-Qusor neighborhood in Dayr al-Zawr city," one of the sources said.
The so-called Syrian Observatory for Human Rights puts the death toll at around 22 without confirming the origin of the strikes.
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.

The US-led air raids also resulted in the injury of hundreds of civilians, some of whom suffered permanent disabilities and had to have their limbs amputated.
The aerial raids caused massive destruction of residential buildings and civilian infrastructure as well.
