Everything about the Osmanen Germania says “biker gang”. They dress like extras from the US biker series Sons of Anarchy. They roam in packs like biker gangs. They tote guns and glorify violence in slick music videos.

Yet despite the look, the 2,500-strong Turkish-German organisation denies the accusations. It says it is focused on “community service”, while pushing a specific political view – that of Turkey’s ruling AKP party, and an admiration for the Ottoman Empire. And anyway, they don’t ride bikes.

Turkish authorities support the actions of the Osmanen Germania and view them as counter-terrorism activities
