Eleven people are dead after a rampaging gunman opened fire at an adult education centre in central Sweden, in what has been called the country’s worst ever mass shooting.Armed police were scrambled to Risbergska School,

The police responding to the attack encountered firing so intense that they struggled to tell how many gunmen were on the scene, an official said.
