At least three people are injured and several are in hospital in a mass stabbing incident near a school in Sweden.
The police are classifying the incident as attempted murder or manslaughter.
According to initial police reports, a fight broke out between two youth gangs who smoked together at a sports facility in Eskilstuna, which lies just over 62 miles west of Stockholm.
An unspecified number of school-age children have been rushed to hospital with knife injuries.
Two of the victims sustained wounds to the upper body, it has been said.
