As I said in my other comment, of course Russian media and gov is untrustworthy, but so is Ukrainian government and media. Both have incentive to push specific narrative: Russians wants to be seen as chivalrous liberators, which requires them to blame civilian casualties on Ukraine as much as possible, while Ukraine wants to be seen as putting up strong resistance in order to keep morale high, and point to civilian deaths as proofs of their invaders savage barbarism.
This means you cannot take any sides claims at face value. At the same time, you shouldn’t just ignore them and close your eyes to propaganda, as you’ll miss important nuggets of truth that are sprinkled throughout the narrative. The more information you get, from all sides, the more likely you will be to be able to piece together what actually is going on.
Hence why the comment above said “Russian media reports”, without five paragraphs of disclaimers that this is not gospel truth, as it assumed that people are able to think for themselves, and take Russian media reports for what they are, which is, while obviously an aggressor’s propaganda, not necessarily a falsehood.
