Police were still puzzling over why the driver, whom they believe to be a Saudi man who posted anti-Islam views, smashed a rented SUV at high speed into a crowd of revelers, killing five and sowing chaos.

In the car of the man who drove into the crowd at a Christmas market in Magdeburg, Germany, on 20 December, a note containing the perpetrator's last will was found. He had considered the possibility of dying and wanted to dispose of his assets.
