That goes both ways.
I saw the video from the start of the fighting and that was UA forces who started to fire upon oncoming forces from the building to the right on the video.
If you mount defenses for something vital for the civilians of your country you should always question how exactly to do that to minimize the damage from the fighting.
Given they took positions in the building, started the fight first, had a prerecorded video for Twitter of how they are under attack[0]...
Sure, I'm just an arm-chair general, but for me it looks what the Ukrainian force decided to fight on the NPP territory and buildings.
[0] go find it you if you didn't saw it. I doubt the first thing what would come to my mind as an operator of a NPP is to fire up a video for a social network.
Regardless of that it is incredibly stupid to do any kind of fighting around a nuclear plant.
