Utter nonsense. The VKS broke the back of the insurgents, especially IS, by targeting their command centres, training camps and income source. This is why the Syrian Army has advanced East, liberated Palmyra is is pressing Raqqa. Just a propaganda piece. No evidence to prove VKS is killing civilians on the scale alleged — SOHR is a discredited one man band. Heck even a claimed Russian airstrike on refugee camp was in fact a rocket attack.
