Is the bombing of hospitals to facilitate a faster spread of refugees into Europe, to keep Europe distracted?
I can't see what else bombing hospitals achieves.
Denies the enemy medical treatment. At the start of the civil war Assad passed a law making it a criminal offence to offer medical aid to anyone fighting his regime. Russia's definition of a terrorist seems to be anyone who isn't in an Assad controlled part of the country, so that includes doctors, nurses, sick kids etc.
