The 25 people arrested in Germany all had links to the far-right Reichsbürger movement.

Christer Mattson, director of the Segerstedt Institute at the University of Gothenburg and researcher in violent extremism, believes that this type of grouping is not limited to Germany in particular.

- This is found all over the world.

A belief in an imminent breakdown for white people is what mobilizes these groupings.

Remarkable event

Mattson describes the event as spectacular.

- That so many people come together to overthrow the German government is remarkable.

He also believes that these kinds of events will increase in the future.

- Yes.

But I think it's important to remember how many far-right terrorist acts we've had and this is another one.

Common to both right-wing and left-wing extremism

According to Christer Mattson, anti-Semitism is recurring within extreme groups, regardless of whether they are on the right or left flank.

- Police and security police do a good job and we don't have to worry.

But we must make targeted efforts in the geographic locations where we know the anti-Semitic background noise exists, because it is common to right-wing and left-wing, as well as Islamist, extremism.
