Seven women and three men died in Sweden's worst mass shooting, police said Friday after completing the identification of the victims. All of the victims, aged between 28 and 68 years old, lived in Orebro,

The police responding to the attack encountered firing so intense that they struggled to tell how many gunmen were on the scene, an official said.

A member of Kasselia's congregation, 29-year-old Salim Iskef, was among those murdered in Orebro on Tuesday in Sweden's first school shooting and the worst mass shooting in the country's history. The gunman killed 10 students at an adult learning centre and then himself.

Sweden's government plans to tighten gun laws following a mass shooting at an adult education center in Orebro, resulting in ten deaths. The suspect, Rickard Andersson, used multiple licensed rifles.

Sweden's right-wing government said on Friday it would seek to tighten gun laws in the wake of the country's deadliest mass shooting at an adult education centre where the attacker appeared to have used several of his own licensed rifles.

Ten years ago, Salim Iskef fled Syria - where Islamic State militants had killed his father - for Sweden, only to be gunned down this week by an unemployed Swedish man with no apparent ideological motive.

The facility offers adult courses, including Swedish language classes for immigrants. Law enforcement officials say the shooter, who Swedish media have identified as 35-year-old Rickard Andersson, may have been a student at the center.

A gunman who killed 11 people, including himself, at an adult education centre in central Sweden may have been a student at the school, police said on Thursday, as they described chaotic scenes after the country's deadliest mass shooting as being like an "inferno".
