STOCKHOLM (Reuters) - A truck ploughed into a crowd on a shopping street and crashed into a department store in central Stockholm on Friday, killing four people and wounding 15 in what the prime minister said appeared to be a terrorist attack. Stefan Hector of Sweden’s national police said the working hypothesis was that “this is an act of terror.”

“We will be working as long as necessary” to determine who was responsible, Stockholm police spokesman Lars Bystrom told The Associated Press. Sweden police officers work at the scene where a truck crashed into the Ahlens department store at Drottninggatan in central Stockholm. “Our thoughts are going out to those that were affected, and to their families,” Sweden’s King Carl Gustaf said in a statement, while European Union chief executive Jean-Claude Juncker said an attack on any of the bloc’s member states “is an attack on us all”.
