Police in Germany raided the homes of 12 people suspected of having formed a far-right group that wanted to attack immigrants and foreigners.
The crackdown on Tuesday comes a day after German Chancellor Angela Merkel met migrant organisations and said fighting racism is her government's "deepest concern".
The 12 suspects, aged between 19 and 57 years, had their homes searched in Schleswig-Holstein and elsewhere in Germany, police in the northern state said.
They allegedly founded the group "Aryan Circle Germany" with others in July in the town of Bad Segeberg in northern Germany.
All the suspects are known to have far-right views, the police said, and are accused of posing with the symbols and slogans of the group for photographs.
The raids of their homes were conducted to find further evidence, police said.
The raids come two weeks after a German man shot dead nine people with an immigrant background at a shisha bar and a kiosk in the town of Hanau, before killing his mother and committing suicide.
Before the shooting, the attacker posted material online that showed a "deeply racist mindset", prosecutors said.
Mrs Merkel said at the time that the shootings had revealed a poison of racism in Germany.
The deadly attack last month was the third in the country to be carried out by a right-wing extremist in less than a year.
A liberal politician was murdered in his home in Kassel in June last year.
Just four months later in October, two people died in the eastern city of Halle after a gunman attacked a synagogue.
At the weekend Mrs Merkel announced the creation of an independent expert group on Islamophobia.
Last week, a network of 60 migrant-related organisations published an open letter to Mrs Merkel accusing her Christian Democrats party and its coalition partners the CSU and the SPD of tailoring their migration and integration policies to win back voters who support the far-right Alternative for Germany party.
