BERLIN—German prosecutors said Monday they now believe that the suspect in a knife attack on a train in November that left four people wounded had a terrorist motive.
The attack took place on an ICE high-speed train traveling from Passau, on the Austrian border, to Hamburg on Nov. 6. Authorities said that the man attacked his victims apparently at random and showed signs of mental illness, but initially said there was no immediate indication of a terror motive.
