RAI News 24's investigation reconstructs what happened in Fallujah during the US assault of November 2004, when nearly all independent journalists were barred and only embedded reporters allowed near the fighting. Correspondent Sigfrido Ranucci gathers testimony from soldiers, doctors, and survivors, along with video and photographic evidence, to argue that American forces used white phosphorus and possibly a napalm-derivative weapon called MK77 against the city's population, not just combatants. Burned corpses show wounds that doctors on camera say are inconsistent with conventional munitions, and former soldiers describe orders and rules of engagement that treated anyone still in the city as a target. The film moves between battlefield footage, hospital interviews, and Pentagon statements denying the allegations, letting the contradictions between official accounts and physical evidence carry the argument. It does not resolve every technical dispute about the chemistry involved, but it builds a detailed case that the siege's civilian toll was deliberately kept out of view.
