Hamas's incursion into Israel on October 7 transformed the politics of the Middle East. Al Jazeera's Investigative Unit (I-Unit) has carried out a forensic analysis of the events of that day - examining seven hours of footage from CCTV, dashcams, personal phones and headcams of dead Hamas fighters, and drawing up a comprehensive list of those killed. In October 7, the I-Unit reveals widespread human rights abuses by Hamas fighters and others who followed them through the fence from Gaza into Israel. But the investigation also found that many of the worst stories that came out in the days following the attack were false. This was especially true of atrocities that were used repeatedly by politicians in Israel and the West to justify the ferocity of the bombardment of the Gaza Strip, such as the mass killing of babies and allegations of widespread and systematic rape.
