Um look at the timestamp on the video and the url it's being played from. Old footage not from the current conflict or it's dates are way off. looks real as in not a cgi edit with explosion edited in. Trees shake, debris comes off moving vehicles and they react to the explosion in typical stunned and expected behavior. The thing that doesn't make sense are the time stamps of 1-03-22 which suggest January. An explosion that large happening in January only seems likely if the current Ukraine government bombed themselves and kept it quite for a few weeks before using the footage.
What are the odds that they with the help of others staged several terror campaigns to breed content for this growing narrative internally? It's starting to appear as if lazy content editors took most of the seen footage from previous conflicts and explosions while some were likely carried out to set doubt in peoples minds, however an attack this large would have been in the media so it was either suppressed for just a few weeks and overshadowed, or those timestamps are off.
Either way a very sus video.
