Germany’s Interior Minister, Horst Seehofer, has banned the right-wing extremist group “Nordadler”, ministry spokesman, Steve Alter, said via Twitter on Tuesday.
Police measures have been activated in four German states, Alter said.
The group is mainly active online.
“Right-wing extremism and anti-Semitism have no place on the internet,’’ Alter wrote.
According to the ministry’s assessment, the group, whose name translates as “northern eagle”, follows a Nazi ideology and operates under several names.
Its members pledge themselves to Adolf Hitler and other high-profile Nazis, as well as using symbols and language from the Nazi regime.
They were also planning a Nazi settlement project with like-minded people in rural areas.
The group is described as highly anti-Semitic.
Its leader expressed sympathy for the attack on a synagogue in the German city of Halle in a public group on messaging service Telegram, according to the ministry.
The attack in Halle saw a 28-year-old German man try to force his way into a Jewish place of worship.
When he failed, he killed two people on the street and at a kebab shop.
He is due to appear in court from July.
The ban on Nordadler is the third ban on a right-wing extremist association by the interior minister this year.
