Let an independent investigations be carried out. God only knows who did it?
But why are you in such a hurry to point your finger at the Russian and assign the blame to them? Taking side.
Based on tales, track records in Dombass and other Eastern Provinces over the past 8 years and IMO these neo-nazi AZOV battalion are capable of commiting such atrocities. That will be my main suspects.
Why do you assumed the Russian soldiers are so stupid to leave such evidences behind?
In urban combat, even with the most sophisticated precision-guided weapons, a civilian to military casualty rate of 1 to 1 is generally expected within densely populated areas. In other terms, a certain amount of civilians unfortunately are likely to succumb to the fighting, even if no war crime is committed, even if they aren't targeted, even if no disproportionate force is used.
I wonder how difficult it'd be for Ukrainian NATO sidekicks and their extremist paramilitary auxiliaries to simply collect corpses of civilians who might have perished in this way, place them here and there to suggest they were simply executed by the Russians, and stage a sonorous propaganda campaign.
Speaking of which, did you notice how this type of propaganda has gained momentum since circa one week ago? As if for the entire previous month, relatively few such crimes were committed and that suddenly, Russians decided it'd be a good idea to go on a rampage, for whatever strange reason.
All of a sudden, in tune with the general propagandistic onslaught, "condom boxes" are supposedly found in the pockets of fallen Russian troops - they didn't really need them before late March, but now they seemingly do. Or, perhaps have the frisking skills of Ukrainian soldiers and neo-nazis taken a sudden, miraculous upward turn. Of course, just purchasing such an item, putting it next to a dead Russian and photographing the scene is inconceivable. It'd be too hard / too costly an endeavor considering how little gain it would offer in terms of conditioning gullible masses against Moscow... not.
Any actual, definitive proof of systematic Russian war crimes? I've not seen a single one to date. Quite peculiar really, considering how in this day and age, at least one such document would have been likely to leak if allegations leveled against the Russian army were accurate. You know, something along the lines of the footage recorded by Australian occupation troops in Afghanistan, which shows them executing multiple unarmed Afghan civilians. But we're asked to believe the latter was an "isolated incident" by "lone wolves" who will be handed "appropriate punishment", while in the case of Russian forces, it's supposedly standard practice despite the lack of undisputable evidence.
Again, we see zero critical thinking among certain sheepish elements who seem happy about getting brainwashed by NATO. It's all about bias and/or pent up resentment (depending on the individual case). Not that it'll make much of a difference on the battlefield though. Gone are the times when the US regime and its clients could "generate" and mold ground reality to their liking through mere media fabrications, propaganda and lies. Now they shout loudly, and they shout a lot but emerging powers keep doing their own thing with success.
This brings me to the concluding remark: the timing of this sudden eruption of 'atrocities propaganda' versus Russia is telling. It hints at severe desperation on the part of NATO and its Ukrainian allies. The Ukrainian armed forces have been inflicted such important losses and their outlook is so grim that they and their western sponsors are reduced to resorting to uncontrolled, all out demonization of their adversary. Some are sore losers, and the sheep among the audience will go on feeling comfortable inside their fictive bubbles.
