(Deutsche Welle) The young man in the video is singing a catchy tune, full of complicated lyrics – and threats: “So come join the ranks/Of the “Islamic State”/A life of obedience/Full of honor and satisfaction and terror to the kafir…” (a derogatory term for non-believers and non-Muslims – ed.).

The message in the video, broadcast online by the jihadist group “Islamic State” (IS), is clear: Those not willing to commit themselves to Islam and submit to its rules will be punished.

The bearer of this “good news,” as it’s called in the video, is. Silvio K. The 27-year-old is the German face of IS, formerly known as ISIS, until it changed its name a few weeks ago. Born in the eastern state of Saxony, Silvio K. first joined the outlawed Salafist association Millatu Ibrahim in Essen before moving to the branch in the nearby city of Solingen.
