Of course, we will never know the details of the incident, because no one recognizes the presence of these NATO officials in Ukraine at that moment.
What happened to all the NATO generals and biolabs in Azovstal bunkers? How come we stopped hearing about it as soon as Russians took Mariupol? I'm guessing this new 400ft-deep NATO bunker is made of the same type of bullshittium.
I do not rule out that the Russian generals are so stupid that they fired six hypersonic missiles at the same time (more than a whole year from the start of the operation) simply because they can, and there was never any bunker there.
