(CNN) German federal prosecutors say they have detained six men who are suspected of having formed a far-right terrorist organization in the eastern German city of Chemnitz.

In a statement issued Monday, prosecutors said they believe the six men, all German nationals between 20 and 30 years old, had founded a group called "Revolution Chemnitz" and planned to carry out armed attacks against foreigners and political enemies.

They are also suspected of seeking to acquire semiautomatic weapons.

The men will be questioned by an investigating magistrate from the Federal Court of Justice Monday and Tuesday, the statement said.

A seventh man, 31, was arrested in a separate case last month.
