BERLIN A man drove a car into a crowd in Germany on Monday, killing two people and injuring 11, police said, adding that a 40-year-old German man was arrested over the suspected attack. Politicians and police treated the noon-time vehicle rampage in the southwestern city of Mannheim as a deliberate act. Germany has been shocked by two other deadly car-ramming attacks since December. "Once again we mourn with the relatives of the victims of a senseless act of violence and fear for the injured,"
