Outside of Israeli sources, expect stuff like the quote below for quite a while.
The Washington Post was unable to independently verify who the weapons belonged to or how they came to be inside the radiology unit.
NYT (about the other/Rantisi raid)
Both videos contained a series of assertions that could not be independently verified. The first includes well-displayed evidence — guns, explosives and other weaponry all arranged as if by police showing the haul from a drug raid — whose provenance similarly could not be confirmed.
At least regarding the Rantisi case, the IDF also posted a video apparently showing an RPG being fired by someone who is then said to run inside the hospital. However, as far as I can tell that video hasn't received anywhere near as much international attention as the raid ones. (Also, no RPGs were claimed to have been found at al-Shifa, just Kalashnikovs and hand grenades.)
About a week before the raid, Al-Jazeera has posted several images showing large holes, some surrounded by burn marks in the top floor and ceiling of the Rantisi hospital. Insofar, I've not been able to find out how the IDF says those happened. Gaza/hospital authorities say they were Israeli missile strikes.
FWIW, there has been a wee bit of contrversy surrounding the placement of some of those in later footage.
CNN compared footage published by the IDF online with footage taken by Fox News, which was granted access to the site in the hours afterwards. IDF spokesperson Lt. Col. Jonathan Conricus leads the tour in the IDF video and a watch on his arm shows the time to be 13:18.
Fox News foreign correspondent Trey Yingst later visits the scene when it is dark. He says in his report it is “the middle of the night.”
Yingst is shown a bag located behind an MRI machine inside the hospital with two AK-47 guns visible on top of it. However, the IDF video filmed earlier shows only one AK-47 gun. It is unclear where the second AK-47 gun came from and why it is not visible in the earlier IDF clip.

The BBC was also granted access to the hospital the following day, November 16, and two AK-47 guns are still visible on top of the bag inside the MRI room.
The IDF told CNN the discrepancy between the military’s own video and the BBC footage was “due to the fact that more weaponry and terrorist assets were discovered throughout the day.”
“Suggestions that the IDF is manipulating the media are incorrect,” it added. “We are acting with full transparency whilst maintaining the safety of our troops and operational readiness.”
