Sweden's worst mass shooting left at least 11 people dead, including the gunman, at an adult education center west of Stockholm as officials warned the death toll could rise.
The gunman's motive, as well as the number of wounded, had not been determined by early Wednesday as Sweden — where gun violence at schools is very rare — reeled from an attack with such bloodshed that police early on said it was difficult to count the number of dead among the carnage.
