LUCKNOW: Two brothers in northern India beheaded their teenage sister and carried her head through their village for having an affair with a cousin, Indian police said.

Officer Rajesh Singh says that after beheading their 17-year-old sister late Monday, the brothers left her body in the street and walked away with the decapitated head.

Police have been unable to find the brothers. Their ages were not clear, but they were both older than their sister.

Singh said Wednesday that at least a dozen people watched as the girl was dragged out of the house, beaten and beheaded, but they did not inform the police. The crime was reported by a local security guard.

Honour killings are common across India, but such brutal slayings are extremely rare.
