I don't know if there were 40 babies,but apparently babies were killed. How many,I don't know. But there were killed.
I was just watching the news and they talked about the 43 minute video reporters from around the world watched. They showed parts of the footage on TV,heavily blurred. And even heavily blurred,trust me,it was very bad.
An Azeri reporter talked about it: "The way they enjoyed killing people....shooting,burning,beheading babies,the raping,the torture".
The scenes I saw on TV,even blurred,were nasty. Very nasty. And they were just a few seconds of stuff,not a full 43 minute compilation.
Other reporters mentioned a burnt baby,others talked about rape scenes as well,executions of children,executions of parents in front of the children,grenade thrown inside a small bunker were a father with his sons was hiding etc.
I gotta tell you something,because you wondered if "we know that Hamas did that". Hamas,is an islamist jihadist organisation which started as an offshoot of the Muslim Brotherhood. I've watched videos of similar "freedom fighters" in Chechnya where Chechens and their Arab friends are torturing,cutting off fingers,beheading and shooting at Russian POWs and I think in some instances civilians too.
I've seen the same kind of people,the so-called "freedom fighters" in Syria,in countless brutality videos. There's footage of Bosnian Muslims and their jihadi Arab allies abusing and posing with beheaded POWs.
Hamas was a supporter of all these.
Even if the security forces accidentally killed other Israelis who were caught in the crossfire,some survivors said Hamas was actively looking for people to shoot and they were hunting a lot of them down and they killed a lot of people.
