A 22-year-old man from the Beduin village of Tel Sheva called police on Monday morning to report that he had stabbed his teenage sister to death.
The 15-year-old girl was found in the family house suffering from serious stab wounds and was pronounced dead at the scene by paramedics.
Negev District Police Spokesperson, Superintendent Nava Tabu said that police have arrested three of the girl's brothers in connection to the crime, including the one who confessed to the murder.
Tabu said that the killing appears to be linked to an internal family conflict and is not linked to organized crime or any ongoing feuds between rival Beduin clans in the area.
She added that on Tuesday morning the brothers will be brought for a remand extension at the Beersheba Magistrate's Court.
