Here is an article from Terrorism Monitor that addresses the recent case of the attempted murder of the Danish cartoonist by a Somali immigrant (the whole story is in this article if you haven’t seen it), but I was most interested in the information that Sweden and Denmark are keeping a closer eye on their Somali communities.
What is clear, however, is that operational networks do exist which link al-Shabaab to Somali diaspora communities in the Nordic countries. Sweden’s security services have repeatedly warned of this threat, while Danish security services have found themselves very busy in the wake of the cartoons. Both have increased their focus on their respective domestic Somali communities. It has been estimated that there are about 20,000 Somalis in each nation, though figures are unreliable. What has alarmed Swedish forces, however, is the growing evidence that non-Somalis are being attracted to the fight from Sweden, something that is supported by a Danish report which claims Somalia is now being seen as the exciting jihad hotspot among young radicals. While the actual numbers are quite small (Sweden claims some 10 nationals are currently in Somalia, and the number from Denmark is unlikely to be much higher), the connection does raise the worrying prospect that al-Shabaab or a similar group might attempt to manipulate the network to carry out an attack in Europe.
