A sober-looking Swedish Prime Minister Stefan Lofven says the deadly stabbing attack at a school in southern Sweden "is a tragedy that hits the entire country."

Lofven says "this affects all of us." He spoke outside the school in Trollhattan after viewing the lobby where an attacker started his rampage.

Lofven declined to comment on Swedish press reports that the attacker had right-wing sympathies, saying police are still trying to establish a profile of the attacker, who was a 21-year-old local man.

The attacker stabbed a teacher and a student to death, was shot in the chest by police, then died Thursday afternoon of his wounds at a hospital.

Police spokeswoman Maria Randsalu said Thursday that the second victim is a male student, but didn't provide further details.
