A driver who rammed a car into a crowded Christmas market in the German city of Magdeburg, killing at least five people and injuring more than 200, has been identified by authorities as a 50-year-old Saudi Arabian citizen who had lived in Germany for more than a decade and worked as a doctor.

Police have arrested a suspect, identified as a doctor from Saudi Arabia who lives in Germany. Police have not cited a motive, but a minister confirmed that the suspect was “clearly Islamophobic.”
