A new documentary from Al Jazeera takes a look at evidence of war crimes in Gaza in the form of social media posted by Israeli soldiers recording and celebrating their own attacks on Palestinians. We play excerpts from the film Investigating War Crimes in Gaza, now available online, and speak to two of the journalists involved in its production, director Richard Sanders and Gaza-based correspondent Youmna ElSayed. “Israelis themselves were telling us precisely what they were doing and why they were doing it,” says Sanders about the evidence the team reviewed. “They don’t think it’s complicated. They don’t think it’s nuanced. Their rhetoric is often overtly genocidal.” ElSayed adds, “They’ve had all the courage to do that because they know that they are not even going to be condemned.”
