If something was posted on April 3rd referencing something posted "Last night", what date was the thing referenced posted?
Like, come on dude, they are literally walking past a burnt-out AFV of some kind. These comments were clearly made in the aftermath, and it even seems like you haven't even absorbed "these bodies and mass graves started appearing in March, when the city was under Russian control" into your noggin yet. At least I think you haven't, since you're posting a video that was recorded after the city was retaken and presenting it like it's supposed to be evidence of who killed who in that massacre.
Also, your first source being an RT guy and your 2nd source being fucking Russians With Attitude is really something. Strong "independent thinker" energy with your choice of sources.
Russians With Attitude at least you don't know what their affiliation is, but they are not at all reliable either, and having it pointed out to you that you are uncritically presenting as the truth what a Russian state media reporter is claiming should give you pause.
