I thought this was a decent video. One of the strongest counterarguments I’ve seen to the failed rocket being the cause of the fireball (rather than merely a coincidence), is the timing. 7 seconds between the rocket breaking up (still unclear if due to failure or interception, someone please correct me if I’m wrong) and impact with the hospital. 7 seconds would certainly not be enough to fall to earth from what appears to be roughly 1km altitude, presuming that the motor is destroyed and that it still had significant upward momentum. So, either estimates I’ve seen of its altitude and vertical velocity are way off, or the rocket would have had to continue burning its motor pointing downward after the failure/interception, OR the explosion of the failure/interception would have had to impart enough momentum to launch the warhead and/or solid rocket fuel straight at the hospital. Not sure which of those 3 scenarios is most likely, I’d guess the last one.
