Bellingcat is a known group tied to certain parties…
They quote an expert whose opinion is based on images from social media which have almost certainly been manipulated and endlessly reposted. And sent by email to Bellingcat?
Other experts are looking at the BDA, results of the strike, and cannot find evidence it was caused by the massive warhead of a targeted KH missile, but rather a much smaller warhead that left the main hospital building with shrapnel marked standing walls and blown out windows, prob from a blast that occurred when the AD missile hit a courtyard and one corner of a smaller building in the complex, which is prob where the deaths (2-3?) occurred. The smallish flash and fragmentation that occurred behind a tall structure the missile flew past, reflected from nearby windows, is also available on videos.
“Dr. Jeffrey Lewis, a nuclear weapons and missile expert at the Middlebury Institute of International Studies at Monterey in California, similarly concluded in an email to Bellingcat that a Kh-101 missile could be seen in footage of the attack posted to social media sites.”
Feel free to post a link to your "other experts". I'll wait...
I suppose the next set of headlines from ISW and Bellingcat could read:
“Inferior quality of Russian weaponry revealed as KH missile fails to destroy a targeted children’s hospital and kill the patients and staff, denying an important victory to Russia as it seeks to inflict genocide on Ukrainian women and children…”
