An independent investigation has determined with “overwhelming certainty” that footage appearing to show pro-Palestinian protesters chanting “gas the Jews” outside Australia’s Sydney Opera House was wrongly captioned, police have said according to Al Jazeera.

Police in the Australian state of New South Wales said an expert from the National Centre of Biometric Science who examined audio and visual files of the protest found that demonstrators had actually chanted, “Where’s the Jews?”

The incorrectly captioned footage of the protesters seeming to invoke the Holocaust at the October 9 rally attracted headlines around the world and prompted the New South Wales government to launch a review of the state’s hate speech laws.
