The men were arrested on Friday, four on suspicion of forming a right-wing terrorist organization last September and the rest of offering them financial support. .

They were planning to stage attacks on politicians, asylum seekers and Muslims, and a federal court judge ordered them detained pending further investigations on Saturday, prosecutors said.

Popular support for far-right groups is growing in Germany, notably in the country’s former Communist east, as part of a polarization at both ends of the political spectrum that is undermining the mainstream establishment that been in government since World War Two.

The men, aged between 20 and 50, named their group ‘Der harte Kern’ (The Hard Core), the Welt am Sonntag newspaper reported on Sunday, saying they had been arrested in six different states.

The suspects, some with blankets draped over their heads, were escorted by police wearing balaclavas and body armor into the Federal Court in Karlsruhe for Saturday’s hearing, Reuters TV footage showed.

Citing investigators, Welt am Sonntag said the men had got to know each other via WhatsApp, a messaging service owned by Facebook, and met up subsequently. The group was put under surveillance in late summer 2019.

In the raids, investigators found stores of materials that could be used to produce home-made bombs, the newspaper wrote.

No further comment was immediately available from federal prosecutors.

German law allows for individuals suspected of being on the verge of committing serious offences to be detained for up to six months, extendable to 12 months in extreme cases, according to legal experts.
