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.

A gunman opened fire Tuesday in an adult education center, leaving about 10 people, including the gunman, dead in what Sweden’s prime minister called the country’s worst mass shooting. A final death toll, a conclusive number of wounded, and a motive hadn’t yet been determined hours later.
