The shooting took place on Tuesday at the Campus Risbergska, an educational centre for young adults in the town of Orebro, 200 kilometres (125 miles) west of Stockholm.

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.

The mass shooting in Orebro on Tuesday has been described by Sweden's prime minister as the worst in the country's history.

"But this hate, it is coming from somewhere." 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.
