I don't like people suffering as much as you do but I cannot conclude from these videos that these people were deliberately attacked by Russians (I mean videos with the footage).

You are posting ukranian sources and as much as u sympathesize with their suffering it is wartime and information is propaganda.

Those are not Ukrainian sources, it's an independent channel in Russian.

If you don't believe testimonials of the people right there, the exact people who were attacked, then I see the only better source: go there yourself. What other evidence is better?

In any case, it's Russia who amassed a shit ton of military all around the Ukraine, and started the invasion.
