Deadly violence is continuing in Sweden, with three people killed overnight in separate incidents near Stockholm and in a city west of the capital.

Three people were killed overnight in separate incidents in Sweden as deadly violence linked to a feud between criminal gangs escalated.

Late Wednesday, an 18-year-old man was shot dead in a Stockholm suburb. Hours later, one man was killed and another was wounded in a shooting in Jordbro, south of the Swedish capital.

Early Thursday a woman in her 20s died in an explosion in Uppsala, west of Stockholm. The blast, which damaged five houses, is being treated by the police as a murder. Swedish media said the woman who died was likely not the intended victim and that the target was the house next door.

Swedish broadcaster SVT noted that the two fatal shootings bring the death toll from gun violence in September to 11, making it the deadliest month for shootings since police started keeping statistics in 2016.
