In the origin of the 35-minute video, a man in a green jacket that suits eyewitness accounts introduces himself as "Anon".
The official stated the suspect changed into a 27-yr-outdated from Benndorf, Germany, who changed into no longer known to police or intelligence and claimed he changed into performing by myself.
By Wednesday afternoon, a police operation was underway in the small village of Wiedersdorf, around 14 kilometers (8.6 miles) east of Halle, according to CNN's German affiliate, n-tv.
Around 3:15 p.m., the police announced that they would evacuate all congregants to a local hospital to offer psychological assistance.
Shots were fired outside a synagogue and into a kebab shop in an eastern German city on Wednesday, Judaism's holiest day, witnesses said.
Social media companies scrambled to scrub footage of a shooting outside a German synagogue from their platforms, in the first major test of their systems since a massacre in the New Zealand city of Christchurch prompted a global outcry.
Stephan B., who also shouted misogynist slogans, is said to have acted alone.
Orthodox Union executive vice president Allen Fagin said in a statement that this "senseless act of anti-Semitic violence was not only a heinous attack on the Jewish community of Halle, but ... yet another example of anti-Semitism in Germany, which continues to proliferate". Anti-Semitic hate crimes have risen significantly in a number of European countries in recent years.
As with Christchurch, full copies and portions of the German video quickly began appearing elsewhere online, shared both by supporters of the gunman's anti-Semitic ideology and critics condemning his actions.
About 2,200 people watched a gunman's video of his attack outside a synagogue in Germany before it was removed from video-streaming site Twitch.

"I hid in the toilet", he said.
He said it took a little while for everyone to understand what was going on.
The man was holding what appeared to be a machine gun and throwing something over the synagogue wall. But soon after, he again drove past the man in the army gear - this time driving a gray Volkswagen Golf. "A heavily-armed perpetrator tried to enter a Synagogue where about 80 people were staying", Seehofer added.
"The assailant shot several times at the door and also threw several Molotov cocktails, firecrackers or grenades to force his way in", he said.
Balliet had packed four kilogrammes (nine pounds) of explosives in his vehicle, and "wanted to enter the synagogue to kill many people", Frank added.
A police tweet Wednesday gave no information on the nature of their deployment in the city but said that initial information is that "people were killed".
However, German authorities a year ago said that 90 percent of anti-Semitic attacks in their country were linked to the far right - a claim that has been disputed.
