An anti-Semitic gunman who shot two people dead in Germany after trying and failing to massacre worshippers inside a synagogue on Yom Kippur was a loner who lived with his mother, it has been revealed.
Stephan Balliet, 27, spent hours sat in front of his computer and was a user of Twitch - a live-streaming service popular with video gamers - where he shared footage his rampage on Wednesday in chilling echoes of the Chirstchurch mosque attack in New Zealand.
It was also revealed that Balliet posted a manifesto online a week ago where he specifically talks about attacking the synagogue in Halle while outlining his plan to kill 'anti-whites', including Jews.
In the wake of the attack, Jewish community leaders criticised German authorities for failing to do enough to combat rising anti-Semitism, while demanding round-the-clock security for Jewish sites in the country.
'The fact that, 75 years after the Holocaust, such groups are gaining influence in Germany speaks volumes,' Ronald Lauder, head of the World Jewish Congress, said.

Balliet was not a known extremist, Bild reported, and appears to have self-radicalised while living alone with his mother in Heldbra, a village around 25 miles from Halle, and spending lots of his time online.
He born in Eisleben, another village close to Heldbra and lived with both of his parents until they divorced when he was 14 years old
After that he went to live with his mother in Heldbra, which is where he was staying at the time of the attack.
Balliet graduated from high school and went on to study chemistry for two semesters at a higher education institution, but had to abandon his studies after a serious stomach operation.
It is not clear exactly what he did for work after quitting his studies, though a neighbour said he was working as a broadcasting technician at the time of the attack.
Video taken of Balliet during the attack suggests he was at least familiar with combat tactics, even if he had no formal training, as he can be seen taking shelter while firing his weapons and moving around as a solider might.
In footage that he streamed online, Balliet also claims he built his weapons himself, suggesting a familiarity with mechanical engineering, though he can also be heard lamenting the fact that his guns keep jamming.
In his manifesto, which was posted online as a PDF document, Balliet included pictures of the weapons and ammunition he used, according to extremism monitoring service SITE.
It also referenced his live stream as well as his objective to kill 'anti-whites', including Jews.
'This manifesto document, which appears to have been created a week ago on October 1, gives yet more indication how much planning and preparation' the gunman put into the attack, Rita Katz, director of SITE, said.

Social media firms faced anger and calls to 'step up' last after graphic footage of the anti-Semitic gun rampage in Germany was streamed live on Twitch and watched by thousands of people.
The 35-minute video was streamed live on Twitch, an Amazon-owned gaming site, and stayed there for another 30 minutes after the broadcast had finished before it was finally taken down.
In that time more than 2,000 people viewed the footage and some of them distributed it further via other social media networks.

The shooter had created his Twitch account two months before Wednesday's Yom Kippur violence.
Last night there were calls for social media sites to take action to stop their platforms being used for violence.
'Amazon is just as much to blame as Twitch for allowing this stream online,' said Hans-Jakob Schindler of the Counter Extremism Project.
'Online platforms need to step up and stop their services being used and in turn, parent companies need to hold them accountable.
'This tragic incident demonstrates one more time that a self-regulatory approach is not effective enough and sadly highlights the need for stronger regulation of the tech sector.'
'We are shocked and saddened by the tragedy that took place in Germany, and our deepest condolences go out to all those affected,' a Twitch spokesman said.
'Twitch has a zero-tolerance policy against hateful conduct, and any act of violence is taken extremely seriously.
'We worked with urgency to remove this content and will permanently suspend any accounts found to be posting or reposting content of this abhorrent act.
'Once the video was removed, we shared the hash with an
