Flags flew at half mast at the royal palace in Stockholm, after a shooting at a community education centre in Orebro left 11 dead. The Prime Minister called it a dark day for all of Sweden, and was joined by the king and queen at a church service in honour of the victims.

Officials in Sweden have vowed to determine why a man killed 10 people, and apparently himself, in an unprecedented attack that's shaken their "society to its core."

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.

Sweden's worst ever mass shooting this week has raised questions about the country's gun laws and widespread gun ownership.
