Car Plows Into Crowd in Berlin, Killing at Least One

BERLIN—A man who plowed a car into a crowd in downtown Berlin on Wednesday, killing at least one person, wasn’t politically motivated but suffered from mental problems, city officials said.

Investigators were still uncertain what triggered the 29-year-old to take his sister’s car and go on a rampage in downtown Berlin, but officials said they had found no evidence of a politically motivated act of terrorism.
