German police arrested a Saudi Arabian man after a deadly car-ramming attack on a Christmas market Friday in which an SUV barrelled through a crowd of revellers at high speed, leaving a trail of bloody carnage. At least two people were killed, one of them a young child, and 68 injured, said authorities in the city of Magdeburg, located about 130 kilometres (80 miles) southwest of Berlin. The suspect was a 50-year-old medical doctor from Saudi Arabia living in the eastern state of Saxony-Anhalt, said regional premier Reiner Haseloff, speaking at a scene cordoned off and guarded by police commandos.
