The US is considering striking eight potential targets in Syria, CNBC reported.
According to the source, those targets include two Syrian airfields, a research center and a chemical weapons facility.
The Syrian military transferred a significant amount of air resources to Russian-controlled airfields, in the hope that Washington would not want to strike there.
Earlier, the US President Donald Trump told Russia to get ready for a missile attack on Syria after Russian ambassador to Lebanon said any US missiles fired at Syria would be shot down.
