Spanish police have arrested 20 people in several raids on suspected neo-Nazis in the eastern Valencia province.
The 20 were suspected of belonging to an illegal organisation which is alleged to have organised attacks on immigrants, officials said.
Earlier this year, more than 20 people were arrested across Spain on suspicion of belonging to the international neo-Nazi organisation Blood and Honour. They are still awaiting trial on various charges.
These include crimes against civil liberties, defending the Holocaust, illegal association, and possessing and trafficking arms.
Saturday’s raids were carried out on several homes and other premises throughout the province, including the city of Valencia.
The group, known as the Anti-System Front, is believed to have stored illegal arms in the premises.
No details have been announced about Saturday’s arrests, and the operation, codenamed Panzer, is said to be still going on.
The group has been under investigation for the last two years.
