The US has reportedly around 2,000 troops stationed in Syria working as "advisers" to US-backed militant groups fighting the Syrian government. State company Rosoboronexport, which controls most of Russia's arms exports, was also subjected to sanctions.

Trump announced the airstrikes Friday night to attack Syria's chemical weapons program. Analysts and diplomats said the strike was unlikely to shake Assad's hold on power or change the trajectory of the conflict.
The president responded to the outrage early on Sunday morning. Putin said such actions will inevitably lead to "chaos" in global relations, according to a readout released by the Kremlin.
