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.

A gunman who killed 11 people, including himself, at an adult education centre in central Sweden may have been a student at the school, police said on Thursday, as they described chaotic scenes after the country's deadliest mass shooting as being like an "inferno".

Sweden saw its deadliest mass shooting on February 4, 2025, at Campus Risbergska in Orebro, when a gunman killed 11 people and injured several others. Media reports have named the suspect as Rickard Andersson, a 35-year-old "loner with extreme social phobia."
