MAGDEBURG, Germany: At least five people were killed in a car-ramming attack at a German Christmas market in the city of Magdeburg that also left more than 200 injured, officials said, and a Saudi man was arrested on suspicion of driving a car into the crowd. The Friday evening attack on market visitors gathered to celebrate the pre-Christmas season comes amid a fierce debate over security and migration during an election campaign in Germany, where the far right is polling strongly.
