"A minute's of silence was observed before kick-off for the Magdeburg market incident, where a car ploughed into a crowd at a Christmas market.
During the minute, one of the fans shouted ‘Germany for Germans’. The culprit of the Magdeburg tragedy is alleged to be a Saudi Arabia national, with about 200 people injured and some dead. This slogan is one often used during the Nazi Germany era.
His words were immediately booed sharply and loudly. This slogan was also followed by a response of 'Nazis out' by other fans in the stadium.
