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.

Swedish police say the shooter who killed 10 people in the country’s worst mass shooting was connected to the adult education center where he opened fire with at least one rifle-like weapon

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