Syrian News Agency released footages showing locals throwing rocks at a military convoy carrying US flags in Khirbet Amo village close to Qamishli.
According to official military spokesperson for Operation Inherent Resolve (OIR) Myles Caggins, the incident came after US-led coalition forces were blocked by pro-Damascus locals at a checkpoint.
The US troops apparently faced resistance from the villagers who threw stones at them.
"They [the Americans] reciprocated with bullets. A young man was killed and two were injured," said the local.
The Russian Ministry of Defense released a statement confirming that Faisal Khalid Muhammad, aged 14, was killed in the incident.
