The men were arrested in early October and, according to prosecutors, are suspected of planning an attack at a railway station near Nuremberg, writes Der Spiegel.
The men are also suspected of sabotage in Romania, where they are alleged to have started a fire in September at a company that manufactures grenade launchers and military equipment. According to Romanian intelligence, the men belong to a network controlled from Moscow.
A third man, suspected of involvement in setting the fire in Romania, was arrested in Poland on Monday, according to the newspaper.
