The man accused of attacking a synagogue in Germany appears to have broadcast his attack on the Twitch live-streaming video platform.
Speaking in English, the man called himself "anon" and announced himself as a Holocaust denier.
"Feminism is the cause of declining birth rates in the West, which acts as a scapegoat for mass immigration, and the root of all these problems is the Jew," he continued.
The footage was verified by the International Centre for the Study of Radicalisation (ICSR) at King's College London after being shared online.
Police said at least two people had been killed in Halle - outside the synagogue and at a nearby kebab shop - and a separate shooting was later reported in a nearby town.
