Forensic experts of the police are seen working in front of the train station in Grafing near Munich, southern Germany, where a man killed one person and wounded three others in a knife attack on May 10, 2016. A spokesman of the police said that the 27-year-old "assailant made remarks at the scene of the crime that indicate a political motive - apparently an Islamist motive". / AFP PHOTO / Christof Stache
