The worst mass shooting in Swedish history was carried out by a 35-year-old Swedish man who lived locally, had been unemployed for a decade and had changed his first and last name, a police source and tax data show.

The gunman was among the 11 people killed in the worst shooting in the history of Sweden at an adult education centre west of Stockholm. On Tuesday, police received reports of a shooting in Orebro, a city 200km (124 miles) west of Stockholm, at 12.33pm local time and engaged in an exchange of bullets with the suspect.

OREBRO, Sweden (AP) — Sweden’s worst mass shooting left at least 11 people dead, including the gunman, and at least five seriously wounded at an adult education center west of Stockholm. The gunman’s motive hadn’t been determined by early Wednesday as the Scandinavian nation — where gun violence at schools is very rare — reeled from an attack.
