FRANKFURT - German authorities on Wednesday arrested five adolescents suspected of forming a far-right terrorist group and said the charges included attempted murder and severe arson.

The arrests follow arson attacks on a community center and a refugee shelter.

Federal prosecutors said in a statement the five were male culpable minors who formed a group which styled itself as the "last wave of defense" to protect the "German nation".

They listed eight German members of the group, disclosing their first names and the initial of their last names, including three who had been previously arrested. Their ages were not disclosed.

The group's "aim is to commit acts of violence primarily against migrants and political opponents to bring about the collapse of the democratic system of Germany", the statement said.

Two of the five are believed to have committed arson at a cultural community center in October in the eastern state of Brandenburg.

Two other members of the group who were arrested previously are accused of breaking a window and firing fireworks into a migrant shelter in Saxony in January.

The statement added that more than 220 police officers were involved in the five arrests and searches of premises across five regional states.

Politically motivated crimes in Germany surged about 40 percent to a record high last year, a report by the Interior Ministry showed on Tuesday, with an especially sharp growth seen in far-right violence.

Deepening political polarization, a series of closely fought elections and the conflict in Gaza were cited as underlying reasons for the growth in violence.
