Kleve, Germany (DPA) -- German police charged Thursday that the grisly death of a 20-year-old ethnic Kurdish woman had been an 'honour killing,' and that her brother had confessed to the crime. Germans have been outraged at a recent series of execution-style honour killings of young women by immigrant families.

The murder of Gulsum S, 20, on a lonely country road one month ago had been made to look as it were a robbery, said police in Kleve, near the Dutch border, as they announced the arrest and remand in custody of the victim's brother, 20, and father.

Prosecutors said Gulsum was lured by a false story to the side road near the small town of Rees on March 2. Her sibling, who was also a triplet to Gulsum, allegedly choked her unconscious with a clothes line. She was then clubbed to death.
