Notice that killing of “innocent civilians” is not mentioned at all the Russians seem to be able to only kill combatants. 600 dead and not one civilian.
Exactly!
Most of the workers at a munitions plant are likely “civilian” — but, they aren’t “innocent civilians”.
For every “combatant” on the ISIL front lines; there are probably more than a dozen non-combatants acting in supporting roles. None of them are “innocent civilians”.
The only innocent civilians in close proximity of ISIL terrorists, are those being held against their will.
