How Sweden’s worst mass shooting unfolded at a small town school - and why police have ‘no clear motive’ one week on - IN FOCUS: As Sweden falls silent for the victims of the Orebro killings their families are still waiting for answers,

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."

The king and queen visited the scene of the tragic event that occurred on Tuesday and Swedish flags were flown at half-mast to honor the victims.

The shooting occurred at a center for adult education in the city of Orebro. The suspect is believed to be among the dead, officials said.

Five people have been shot at a school in Sweden as authorities warned the danger was not over while armed officers rushed to the scene. Armed police descended on the Risbergska School, an adult educational institute in the city of Örebro some 200 km (125 miles) west of Stockholm on Tuesday.

Police say around 10 people have died in a shooting at an education campus in the city of Orebro. It is the worst school shooting ever to happen in Sweden, where school violence is rare. The suspected gunman is believed to be among the dead.

At least 11 people died, including the gunman, and at least five were seriously wounded in a shooting at an adult education center west of Stockholm.

Government offices, schools and workplaces fell silent in Sweden at midday on Tuesday in remembrance of the victims of a mass shooting at an adult education centre last week when a gunman killed 10 people before turning his weapon on himself.

A minute's silence was observed across Sweden on Tuesday to honour the victims of a deadly shooting at an adult education centre in the city of Örebro. The minute's silence was held in Örebro and several other Swedish cities at 12 pm (1100 GMT).
