Aftenposten reports that there has been a sharp escalation in youth gang warfare in Oslo the last few days, focusing mostly on three more or less formal gangs with territories in Søndre Nordstrand, including Holmlia, Mortensrud and Bjørndal; Groruddalen, including Furset and Trosterud; and central Oslo, including Grønland, Tøyen, and Grünerløkka. In other words, vast sections of Oslo east of Akerselven.
The police take this seriously but concede they have no idea what the context or motivation for this escalation might be. The leader in Youth Against Violence, Farid Bouras, says that the reported violence probably understates the problem, as gang members are unlikely to report incidents. There is also concern that the youth gangs are extensions of organized crime in Oslo.
