LONDON — The English Football Association has condemned "insulting" chants by fans at Wednesday's game against Germany referencing past wars between the countries.

Before the 1-0 loss on Wednesday, England fans booed the Germany anthem and sang distasteful songs referencing the First and Second World Wars.

FA chairman Greg Clarke said on Thursday "the behaviour of a section of the England support in Dortmund last night was inappropriate, disrespectful and disappointing."

Clarke expressed frustration that supporters chanted "songs that could be regarded as insulting to others" and said the FA is trying to address the problem with fan groups.
