A teenager went on a violent knife attack in a school, resulting in the death of one girl and injuries to three others.
According to reports, the 15-year-old assailant carried out the stabbing spree in France and was eventually subdued by courageous teachers.

The tragic incident took place on Thursday afternoon at Notre-Dame-de-Toutes-Aides, a private school in Nantes.
The boy is said to have arrived at the school and ran into two classrooms as he carried out the heinous assault.
Four people were stabbed in total with one female student dying from her injuries.
Two remain in critical condition with the fourth only suffering minor stab wounds, according to BFM TV.
Cops confirmed the teen was quickly overpowered by teachers just as police arrived.
A police spokesperson said they are still investigating the incident but officials don’t believe it is terror related.
It is unclear if the student attended the school or not.
He was also not on any police or intelligence radars before the attack.
French Interior Minister Bruno Retailleau is expected to arrive at the school later this afternoon.
