Another attack using a knife in Germany
This is another attack in Germany in recent weeks. On Saturday evening, a 30-year-old woman attacked passers-by in the center of Munich, hurting two people. The attacker was shot by the police and died in the hospital as a result of the wounds. The motives she followed are not known yet.
Two weeks ago, a 29-year-old woman wounded 18 people at one of the platforms of the Main Railway Station in Hamburg.
