the shooter filmed himself and published his video live on the internet

"We have done as soon as possible to remove this content, and we will suspend all the accounts that will post or repost images of this abominable act", said a spokesman for Twitch interviewed by AFP.

She did not mean immediately how long the video had been online, simply stating that the Amazon subsidiary was investigating the exact circumstances of the broadcast. The modus operandi is reminiscent of the attack on two mosques in Christchurch in New Zealand in March by an Australian far right, which had killed 51 people.

Antisemitic attack of far right

The author of the shooting is a 27-year-old German with far-right ideas, according to security sources quoted by the German news agency DPA.

He was not known to the police, according to sources of security services quoted by Der Tagesspiegel. He would not be a Muslim either.

According to the website of the Leipziger Volkszeitung, the arrested man is seriously injured and undergoes surgery.

Earlier in the afternoon, Halle University Hospital reported that it had received two wounded, one of whom was shot. However, the establishment did not provide details on the identity of these people.

He placed explosive devices in front of the synagogue and tried to enter. A woman was shot outside the building and a man was later killed in a nearby Turkish restaurant.

For the German Minister of the Interior, Horst Seehofer, we can assume that the events correspond to "an anti-Semitic attack"and that she had far-right motivations."According to the Federal Attorney General, there is enough evidence of a possible past of the extreme right", he said.
