According to Eli Beer [interviewed on TBN], after the Hamas attack on Oct 7, Israeli first responders ran into a scene where multiple children had been decapitated on same location and "we were trying to figure out which head belongs to which child".
Beer makes exactly the same claim in another, much longer speech/video at the Republican Jewish Coalition Annual Leadership Summit (around 32:50) where he also implies he personally saw that scene:
I saw little kids who were beheaded. We didn't know which head belonged to which kid.
Are the other accounts (and/or material evidence) confirming this event?
Note: there's a separate question here about any decapitated babies. This claim is about children, so not the same (could be substantially older than babies), and furthermore the claim is that there was a mass decapitation of children in the same location.
