Three people were killed in a shooting in the Swedish city of Uppsala on Tuesday and a murder investigation has been launched, police said.

Three young people were gunned down at a hair salon in Uppsala, Sweden, in what may be the latest act of gang-related violence.

A masked gunman opened fire at a barbershop in the Swedish university town of Uppsala, 40 miles northwest of Stockholm, shooting dead three young people in an apparent gang killing. A suspect is under arrest.
