Al Jazeera’s Investigative Unit has just released a documentary on Israeli war crimes, based in part on social media posts from Israeli soldiers themselves. The documentary begins with the Palestinian novelist Susan Abulhawa, as well as footage of the Al-Awda school massacre in July, when Israeli troops killed at least 31 people at a school sheltering displaced Palestinians. The moment the bomb exploded was captured on video by someone recording a youth soccer game in the Al-Awda school courtyard.
