The Russian teenager was planning to commit a terrorist act in Oslo
The police of Norway has detained 17-the summer Russian in the case of the preparation of the explosion in Oslo. About it reported the edition "The Independent". A primitive explosive device was discovered on the evening of 8 April in the center of Oslo near a metro station.
Thank goodness they were able to disarm it and avoid another tragedy. This is just while the Stockholm attack is still fresh in people's minds. They surely are cranking up on the attacks and as one observer put it, they were all "lone wolf" attacks. Stockholm, Berlin, etc... This seem to be increasingly the preferred choice now. Just keep your forces inside the House of Peace and let some radicalized nut do the attack on the land of the kuffars.
You can re-phrase your wording as "Muslim teenager".
What a mistake.
Muslims are fighting terrorists.
Maybe "Islamist" or "Muslim fundamentalist" would be better choice of words. Points at their declared reason for violence while not dragging all Muslim along. Unfortunately since the media always try to avoid the M and I word, he'll probably just be labelled "Russian teenager" or just "teenager" in the news.
