Abu Usama appears to be in his late 20s. With a neat ginger beard and a rifle slung over his shoulder, he addresses fellow Muslims back in Germany from his new home in northern Syria. In a 9-minute video released by the Islamic State of Iraq and Syria (ISIS), he explains that he took his name from Osama bin Laden, because "he hit the head of injustice, and he is the one who terrorized [the West] as they terrorized us. Since they did not stop doing this, we will treat them in kind." He asks his audience: "Are you happy with your life in Germany? Going to the nightclubs and having female friends?" according to a translation of the video by SITE Intelligence.
