The UN did not find photo and video evidence of any rape happening you clearly did not read the report.
Israel showed them pixelated photos from ZAKA with a made up backstory where if you let the Hasbara imagination fill in the details enough you can imagine rape happening.
Even Patten had to conclude that there were in fact no photos or videos of actual rape because blurry pictures with Hasbara descriptions don't count. The report specifically mentioned that the blurry pictures are not evidence of rape depictions
The only reason photos and videos are mentioned is to trick people that cannot read well or won't read the whole report into thinking there's evidence because the Patten report was an israeli invited tour. There is none.
