Paris (CNN)A teenage student killed a teacher at a school in southwestern France on Wednesday, authorities said.
The 50-year-old female teacher died from injuries inflicted by the attacker, a 16-year-old student, said French government spokesman Olivier Veran.
The assailant was a teenager suffering from psychological troubles who claimed to "be possessed" after stabbing the teacher in the chest, according to CNN affiliate BFMTV.
BFMTV reported that, following the attack in the town of Saint-Jean-de-Luz, the assailant fled into a neighboring room where he told a teacher that a voice had told him to commit the attack. The teacher took the weapon from the student and remained with him until police arrived, BFMTV said.
