The problem with this story is the Kh-47M2 Kinzhal missile is not a ground penetrator. It's a hypersonic missile that is either conventional or nuclear. It's for surface targets only and is not a ground penetrator. The Kh-59MKM is the newest "bunker buster" Russia has, and I'm not sure of its deployment history, but that missile is rumored to be capable of doing what this video is saying.
The very high speed of the [Kinzhal] missiles also makes them more able to penetrate heavily armored targets, such as the underground weapons depot in western Ukraine said to be the target of the latest strike.

Interesting. I learned something new.
"Kh-59MKM – penetrator version that eliminated the seeker section and fitted a 360 kg (790 lb) warhead, able to penetrate 3 m of reinforced concrete."
