In the low-level buildings of Campus Risbergska in Orebro, a 35-year-old man stalked the corridors looking for his targets.

Syrians and a Bosnian were among the 10 victims of a gunman who carried out the worst shooting in Swedish history, at a school in Orebro on Tuesday. It was the first information about those murdered in the attack, and it came from two embassies rather than police, who only said there were victims of a number of nationalities.

The shooter who earlier this week killed 10 people in Sweden's worst mass shooting was connected to the adult education center where he opened fire with at least one rifle-like weapon, law enforcement officials said Thursday.
