Magdeburg's Christmas market is a sad sight. This should have been the busiest weekend of the season, but the whole area has been cordoned off and all the stands are shut. Police are the only people walking around the boarded-up mulled wine and gingerbread stalls. On the pavement, red candles flicker, tributes laid for the victims.

Officials say four women and a 9-year-old boy were killed when a Saudi doctor drove into a Christmas market teeming with holiday shoppers in the German city of Magdeburg on Friday.
