You will not find such material through official sources. They are atrocities and should not be circulated for many many good reasons. The photos and videos that do exist are spread around by Hamas themselves who have a sadistic satisfaction in seeing jews, abused, tortured and dead.
I am not talking about the pictures specifically, I am talking about the news as a whole. If it has been confirmed by an independent news agency, that would be an indication, that it might be true.
Uh huh. Sure.
If they actually had the legit pictures they'd be putting it out on every channel possible. It could only help their cause.
The meme made a claim! I don't see you contesting that. And again, go do your research. Find groups who are willing to share such content. I'm not, period.
