Syria's state news agency, SANA, reported that the fighter jets pounded residential neighborhoods in the town of al-Souseh and regions near the town in Southeastern Deir Ezzur, killing and wounding a number of civilians and destroying their properties.
The US-backed Syrian Democratic Forces (SDF) also launched artillery attack on al-Souseh.
The Arabic-language website of Sputnik quoted a military source as saying on Thursday that 2 US-led coalition F-15 fighter jets targeted the positions of SDF in Eastern Deir Ezzur.
He added that the US warplanes' target was ISIL's strongholds in areas near the town of Hajin but they attacked the SDF, killing 6 Kurdish forces and wounding 15 others.
The source said that the incident happened due to a lack of proper coordination and unprofessional performance of the US forces, adding that it indicated failure of the US policies in Syria and creation of more problems in the region.
