Germany has banned a neo-Nazi group that voiced its support for the attacker in the deadly shooting in Halle last October, the country's interior ministry announced Tuesday.
The group, known as the Nordadler (Eagle of the North), is said to have mostly been operating on social media and was targeted in police raids.
"From this morning, police measures are underway in four regional states," a ministry spokesman said on Twitter, adding that "right-wing extremism and anti-Semitism no longer have a place on the Internet."
Raids were underway in North Rhineland-Westphalia, Saxony, Brandenburg and Lower Saxony, the DPA domestic news agency reported.
Nordadler was the third small, far-right group to be outlawed in Germany this year following several attacks, including a shooting at a synagogue that left two dead in the eastern city of Halle last October, although the fatalities occurred outside of the complex as the assailant failed to gain entry.
The group uses the symbols and language of Adolf Hitler's Third Reich to voice nostalgia for the Nazi regime and anti-Semitism.
Nordadler, which had plans to set up a neo-Nazi community in the German countryside, expressed support for the Halle attacker who admitted to anti-Semitic and far-right motives.
Last February, another gunman shot dead nine people of migrant origin in the central town of Hanau.
