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

The king and queen visited the scene of the tragic event that occurred on Tuesday and Swedish flags were flown at half-mast to honor the victims.

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 center where the attacker appeared to have used several of his own licensed rifles.

The shooting occurred at a center for adult education in the city of Orebro. The suspect is believed to be among the dead, officials said.
