Their online videos often feature scenes of violence – improvised explosive devices going off in Afghanistan, snipers hooting at American troops or scenes of jihadists training in an unidentified wilderness. The video is often coupled with appeals to the Quran and statements by the leader of an Islamic extremist group.
