A gunman opened fire at an adult education center in the Swedish city of Örebro on Tuesday, killing at least 10 people in what the country’s prime minister called the “worst mass shooting in Swedish history.

But the scale of the loss of life means the public and politicians want answers from the police now. More than 100 specialist officers are involved, on a local, regional and national level. Unconfirmed reports in the Swedish media say the gunman was a 35-year-old local man who legally owned a gun.

One day after the killings at an adult educational center, some gathered to lay flowers and come to grips with the violence.

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."

Witnesses who survived Sweden’s worst mass shooting have described horror and panic that gripped an adult education center west of Stockholm as the gunman killed at least 10 people.

The authorities said that at least 11 people were killed and that the suspect was believed to be among the dead.
