There's a ton of information coming out from a bunch of different sources and it's difficult to keep track of who's said what and who has evidence of what. This thread is to keep track of who's making what claims, who has what evidence, and discussion surrounding those.
For top-level comments, please separate into two categories:
Evidence (videos, facts, circumstantial evidence, etc.) that we can validate, invalidate, or provide supporting sources for
Claims (IDF, Hamas, Western media, etc.) that we can prove or disprove using current evidence

It's established fact that Israel was operating aircraft near the hospital, that Israel was striking targets near the hospital, that Israel had indicated that they would strike the hospital, that Israel had striked the hospital in the past, and that Israel had targeted multiple hospital staff in the days leading up to the strike.
It's currently up to debate, but many indications suggest that Israel's message has changed multiple times. The initial claim was that the attack was on Hamas operatives within the hospital. The claim afterward was that this was a Hamas misfire (using demonstrably falsified audio evidence).
The videos show that a single large explosion triggered whatever happened, not a sequence of smaller explosions or secondary detonations. The video circulating of a Hamas rocket "misfire" is more indicative of a MANPADS launch given multiple comparable flight paths from other MANPADS. It's a clear usage of a multi-pulse rocket motor, something Hamas does not have domestic capability for but does have access to through Iranian MANPADS. An Iranian Misagh-2 fires a missile with less than 2kg of explosives and less than 20kg of total weight.
At this stage, my most likely conclusion is that the damage was the result of an airburst bomb.
The light could maybe be explained by the difference in exposure. The TV clip seems a bit too dim to make out the rockets, but the other one is kinda bright. The buildings are pretty bright and that small sliver of light from that window might not make it out properly. I would really like to know what's up with this camera or these cameras. Maybe this is the spot for journalists to put up unattended 24h livestream cameras, the terrible quality and the timestamp would suggest that. If there's a person there though, it could explain how the picture changed in an hour. Maybe someone came by and fixed it in the meantime, like they only check on this camera every so often or they were out for a coffee or something. Would be really important to find the source of that other video.
Someone who knows how to do video editing should try to line up the pattern of the rocket launches. If they match exactly that's pretty much proof one of the videos was doctored.
