Two men died and six were in hospital after a mass family brawl in the Swedish city of Norrkoping, police said Tuesday. Police said guns, knives and sticks were used during the fight that involved at least 30 people late Monday in the city south of Stockholm. Five people were detained on suspicion of murder, attempted murder or as accessory to murder, dpa quoted Anne Asp of the Norrkoping police as saying. "The brawl was due to an old family feud that escalated," Asp said. The two deceased were brothers, aged about 35 to 40, she said. Six others have been admitted to hospital for gunshot or knife wounds, Asp said.
