Swedish police say about 10 people have been killed in a shooting at a school for adults in the city of Orebro, including the suspected gunman.

Sweden is reeling from the country's deadliest mass shooting this week as investigators continue to look into the gunman's motive.

The shooter targeted a center that serves migrants seeking to integrate into a country that had already reversed its liberal migration policies.

Police said “around 10 people” were killed in a shooting at a school in central Sweden on Tuesday, with the suspected perpetrator believed to be among those dead.

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.
