From Xaviez Titelman, It is a missile. He’s explaining here (in franch but YT can translate.).
What he says is that the white plume left to the plane falling trajectory is a missile signature, with a very white propulsion fume, then a grey part corresponding to explosion, and from his experience, it’s a tunguska or BUKSAM.
Another thing in the video is that the plane have been routed outside airways but the russian control before its destruction, very likely to ensure a good shot.

When I watched that clip it reminded me to what we usually saw after missile hitting target when served in anti aircraft unit. However, I don’t know how it looks like when a bomb explodes on board of aircraft.
Here at 13:36 is some interesting stuff
Supposedly happened around 30,000ft.
