In particular, it examines and analyses the visibility of Finland and persons connected to Finland in jihadist online communication and investigates the types of content persons who are or were living in Finland have produced and disseminated content on different online platforms and channels. The report focuses on jihadist material that was openly available online during this period. It also contains a section describing the development of jihadist online communication more generally, thus helping to put observations in a broader international context.
