"Werewolf Commandos" in Europe

Home-grown terrorism persists.

Authorities in northern Europe have raided the homes of several alleged right-wing extremists. Investigators suspect their group, dubbed "werewolf," of planning terrorist attacks on German soil.

Police in Germany, the Netherlands and Switzerland swept into homes, offices and jail cells early on Wednesday to search for clues of a terrorist plot aimed at the German political system. They conducted a raid which targeted six suspects, according to Germany's federal prosecutor.

Some 50 police personnel took part in the searches in Germany, which spanned across the northern cities of Hannover and Hamburg, and reached into the northeastern state of Mecklenburg-Western Pomerania. It was not immediately clear in which cities the Dutch and Swiss searches occurred.

Authorities believe there is a chance the Werewolf group is planning a large-scale attack similar to the murderous 2011 rampage of radical right-winger Anders Behring Breivik when 77 people were killed.
