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 as officials warned that the death toll could rise. 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 with such bloodshed that police early on said it was difficult to count the number of dead among the carnage.
