Anti-racism campaigners are staging vigils across Germany to commemorate the victims of a far-right terror group whose existence came to light a year ago.

Organizers have called memorial events in two dozen cities Sunday to remember the victims of the National Socialist Underground.

The group is suspected of killing at least nine men and a policewoman during a seven-year murder spree that began in 2000.

The male victims all belonged to ethnic minorities and for years German authorities attributed the murders to immigrant gangs.

The investigation took a dramatic turn when two fugitive neo-Nazis were found dead in an apparent murder-suicide on Nov. 4, 2011.

The third alleged core member of the group, Beate Zschaepe, is in custody pending trial.
