A German right-wing extremist was sentenced Monday to life in prison for killing two people during a shooting rampage near a synagogue on Yom Kippur last year – recording the sickening attack and streaming it online.

Stephan Balliet, 28, was convicted of two counts of murder, 66 counts of attempted murder, bodily harm and incitement in the attack outside the Jüdische Gemeinde Halle temple as worshipers were inside observing the holiest day in Judaism.

Judges at the Naumburg state court found him “seriously culpable,” which means he will be effectively barred from early release after 15 years.

As Judge Ursula Mertens announced the verdict for what she called a “cowardly attack,” Balliet, his head shaved and dressed in black, showed no reaction but took notes, according to the dpa news agency.

In a chilling echo of the Christchurch, New Zealand, mosque massacre in March 2019 — which was shared on Facebook Live — Balliet livestreamed his attack in a video on Twitch as he failed to gain entry into the temple.

The Oct. 9, 2019, rampage is considered one of the worst anti-Semitic attacks in Germany’s post-war history.

Balliet introduced himself as “Anon” before going on an anti-Semitic rant that also included attacks on feminism and immigration. He also posted a screed against Jews before trying to shoot his way into the synagogue.

During his trial, which began in July, Balliet admitted he wanted to enter the temple and gun down all the 51 people inside.

When he was unable to open the heavy doors, he shot and killed a 40-year-old woman in the street and a 20-year-old man at a nearby kebab shop.

He also wounded several others before fleeing the scene, but was caught about 1½ hours later as he abandoned a stolen taxi after an accident.

Mertens said there had been several unbearable moments during the trial and that Balliet hadn’t shown a shred of remorse, adding that society needed to be protected from him.

“You are a fanatical, ideologically motivated lone perpetrator,” the judge told him. “You are anti-Semitic and xenophobic.”

Balliet apologized to the court for killing the woman, saying: “I didn’t want to kill whites.”

At the end of the court session Monday, Balliet threw an object — apparently a rolled-up file or folder — toward representatives of victims who had joined the trial as co-plaintiffs, according to dpa.

Four guards then grabbed him and carried him out of the courtroom.

Josef Schuster, the head of Germany’s Central Council of Jews, said the verdict marked “an important day for Germany.”

“The verdict makes clear that murderous hatred of Jews meets with no tolerance,” he said in a statement. “Up to the end, the attacker showed no remorse, but kept to his hate-filled anti-Semitic and racist world view.”

Mark Lupschitz, a lawyer for nine of the co-plaintiffs, told Agence France-Presse that he was “relieved” by the verdict and called the proceedings both “stressful and empowering” for the intended victims.

A government spokeperson, Ulrike Demmer, told reporters that the rampage “showed us how important it is to even more decisively continue the fight against anti-Semitism, xenophobia and hostility to democracy.”

Israel’s ambassador to Germany, Jeremy Issacharoff, said the attack remained “a very, very alarming moment in German history”.

“If that guy would have been able to get into a synagogue… it would have had a tremendous impact on German identity after the war and the fight against anti-Semitism,” he told AFP.
