The article that ClathrateG sent describes a drone attack Ukraine did on an airbase which had MILITARY aircraft and shells. What they (edit: they = Ukrainians) did not know was that Russia also was hidding nuclear shells which exploded, which led to the attack doing more damage and unintentionally hurting civilians.
Most likely has nothing to do with that specific woman. Maybe just anti-hair color ragebait? Some are saying Ukrainian soldiers are war criminals for this, probably didn't hear how Russians are INTENTIONALLY bombing hospitals. Of course just saying "the other guys are worse" is problematic, but I repeat Ukrainian soldiers did not try to hurt civilians.
Here is a video about it: https://youtu.be/OODJsg6AyQg
Unlike Russia, Ukraine mostly only targets military facilities. Of course there could be civilian casualties, like maybe in the oil refineries they bombed inside Russia, but they DON'T target civilians, but the strategic positions which may have civilians. Meanwhile Russia DOES target civilians in hospitals and schools.
I admit there are probably civilian casualties caused by Ukraine, but its an ant. Now lets address the elephant in the room: Russian caused civilian casualties and war crimes.
