Police say a man carrying two knives stabbed one person and threatened several others in the center of Oslo on Wednesday. The incident occurred outside one of the city’s biggest shopping centers when an argument got out of hand, according to police. The unnamed man in his 30s stabbed one man in the arm and charged at several others. A policeman drew his gun and told the man to drop the knives, a witness told Norway’s national broadcaster NRK. The incident is not believed to be terror-related.
