There was nothing remarkable about the friendly, polite man with the long, dark beard, sporting a grey hoodie and blue jeans. Nothing, at first sight that is, to distinguish him from the young parents pushing prams and students milling around the busy, central intersection in the tranquil western German city of Bonn he had suggested as a rendezvous point.
But, given his contacts and statements in the past, one source in the German domestic intelligence agency told DW, he was "likely" part of the jihadi spectrum of Salafism, one of the most conservative branches of Islam.
Or, as Said El E., who goes by the name of Abu Dujana, told DW, the "only true religion ... the only truth there is."
He belongs to a movement that has spread rapidly across Germany and then Europe, coinciding with the rise of the "Islamic State" (IS).
