Two of the deceased were shot and the other victim died in an explosion that damaged five houses. The police described the incident as murder.
The SVT chanel reported that the two fatal shootings brought up to 11 the number of deaths caused by gun violence in September, which was the deadliest month since the police have been counting this statistic.
Speaking to TV4, Justice Minister Gunnar Strömmer called the event ‘deeply tragic.’
Police reported the arrests of two people for alleged links to the explosion, whose shock wave could be perceived by seismic monitoring stations some 20 kilometers away, according to the TT news agency.
