A NEO-Nazi maniac vowed to "kill as many Jews as possible" before he murdered two in a gun and grenade attack on a synagogue yesterday.
The gunman - who is now in custody - live-streamed the chaos on social media after mounting a camera to his helmet and opening fire in the city of Halle, Germany.
The suspect, named locally as 27-year-old Stephan Balliet, also turned the camera on himself as he launched into a hateful rant about Jews and feminists.
At one point he told viewers his mission was too "kill as many anti-whites as possible, Jews preferred."
Today prosecutors said the suspect was intent on carrying out a "massacre" when he attacked a synagogue with 80 worshippers inside celebrating Yom Kippur, the holiest day of the Jewish year.
Cops are also investigating how he got hold of materials for 9 lbs of homemade explosives found in his car.
Germany's chief federal prosecutor Peter Frank said: "What we experienced yesterday was terror," adding the gunman wanted to create a "worldwide effect" by livestreaming his attack
Heiko Maas, Germany's minister for foreign affairs, said last night: "A shooting at Halle synagogue on Yom Kippur hits us all in the heart."
Worshippers were barricaded inside the synagogue as the maniac shot at the door and tried to storm in.
He failed to get inside, threw homemade grenades under a gate to a Jewish cemetery and shot dead a woman who got off a tram.
He was then attacked a kebab shop where another victim was shot dead as staff and diners cowered in a toilet.
Images later emerged showing a maniac stalking the street outside the takeaway with a shotgun.
One witness said: "The man came up to the doner shop, he threw something like a grenade, it didn't explode, and he opened fire with an assault rifle.
"The man behind me must have died... I hid in the toilet."
Video also showed the man wearing a helmet with a mounted camera firing from what appears to be an adapted shotgun from behind a car.
His 35-minute livestream footage was shared on Twitch and other networks where it was viewed by thousands. The Sun Online has chosen not to show it.
The attack has chilling similarities to the methods used by far-right gunman Brenton Tarrant during the Christchurch massacre.
Tarrant infamously used a GoPro camera to live-stream himself killing of 51 people and wounding 49 at two mosques.
It is thought that far-right extremists have already embraced the Halle gunman as a "saint", the same title that was also given to Tarrant.

Cops in the city of Halle and nearby Landsberg earlier warned locals to stay inside while they hunted down the suspect and other potential members of the armed gang.
They now believe there was only one attacker, who is being held on suspicion of two murders and nine attempted murders.
The first attack took place on Humboldtstrasse in Halle, which houses a synagogue and Jewish cemetery.
It came after a series of police raids the previous night in connection with threatening far-right emails sent to mosques, political parties and migrant reception centres across Germany.
