About 17:20 in. Again they do mention the race and the link with migration as well. They also talk about how this was provoked questions/anger at the refugee policy of the German government.
I couldn't find anything on Radio 5 site's admittedly although most of their stuff appears domestically targeted (so much about Labour's reshuffle). However I have linked to multiple BBC Website stories, two BBC news reports, a BBC Newsnight report, a BBC News at 10 report and a, albeit brief, Radio 4 report so I am not convinced there is a BBC editorial policy not to mention it.
