After the shooting last year, the whistles sounded, signaling that the children would quickly enter the school and close the doors.

But then Janna and other children had already heard or witnessed the murder.

Janna's mother Amna Rasas says that her daughter cried and had difficulty sleeping afterwards.

She also worries about everyone else who has been around.

- Poor child.

The children need a psychologist, the mother says when we meet after a school day when they have to pass the murder scene on the way home.

Janna's eleven-year-old big sister just passed the killers when the victim was shot.

A ten-year-old girl, who had just managed to escape the bullets, later told the police that she really wanted to help the shot man, but that she did not dare because she did not want to die.

17 young people have been murdered since 2018

Husby is located in the violent Järva area in northwest Stockholm.

Since 2018, it has been shot on 87 occasions in Järva - of which 63 have been within 150 meters of a preschool or school, SVT's survey shows.

This means that more than seven out of ten shootings have been close to the children's environments.

Seventeen young men have been murdered during that period - an eighteenth death was added in January this year, in the latest fatal shooting.

That time in a stairwell in Rinkeby.

In addition to near schools, several of the murders have also occurred in stairwells, courtyards and restaurants.

This affects the children's concentration in school, but also how they see their own future.

In SVT's documentary Who will save the children, ten-year-old students say that they are worried about being shot themselves.

Happy Hilmarsdottir Arenvall is the primary school principal for the Järva area's thirteen municipal primary schools.

She fights from her side for more people to learn Swedish and pass school, so that they have better choices in life and are not attracted to crime.

The gang conflicts that take place in the area affect parents who often flee war for the sake of their children.

- I think it is terrible that we have allowed a society and children need to be exposed so that they can not live in a safe, quiet environment that all children have the right to, she says.
