I watched it, which is why I can unequivocally state that there is no context given. Try posting something from a reputable news source that is actually part of a news story about this “bombing,” and not a snippet of a video from Reddit, FFS.
I think the context you are missing is that the video was posted as a response to someone else's claims.
The video shows the toll on civilians of bombing and shelling non-military targets.
The thread you are reading is not about any "bombing" but it is about some stray fire near a nuclear power plant, in case you hadn't noticed.
As to the "reputable news source" you must be one of those people who wants to hear some talking head in a studio at some fake news outfit in New York City tell you what to think. You can learn much more by looking at actual video from inside Ukraine.
