Six consecutive missiles fell, and it's uncertain what kind of mood or state the people in the building were in, or how many of them were still able to move.
The command center of the Assyrian Group must have been completely rendered useless, but there's an underground bunker from the Soviet era, and it's unclear if anyone survived because of it.
Logically, a structure that can withstand a nuclear strike shouldn't be able to withstand a ground-penetrating bomb, especially since this isn't an aircraft-dropped bomb; it's the warhead of a surface-to-surface missile, falling at speeds over Mach ten, much faster than the speed of unguided aircraft bombs. Naturally, its power is much greater too. Even if there were six underground levels, it should have penetrated them all.
