The first EU Terrorism Situation and Trend Report TE-SAT 2007 produced by Europol was presented 10 April 2007 in the European Parliament in Brussels.

The report identifies three continuing trends within terrorism in EU countries: separatism, anarchism and Islamic extremism. While the vast majority of terrorist attacks reported in Europe in 2006 were separatist in nature, the largest number of arrests were linked to Islamic extremists. The report indicates that France, Spain and the UK are the countries most severely affected by terrorism, and that most terrorist incidents in Europe are designed to avoid human casualties.

The largest single category of incidents in 2006 was separatist attacks in France and the largest single category of arrests was also of separatists in France; nearly all related to the island of Corsica. Separatist attacks in Spain accounted for over one hundred incidents, despite the ceasefire maintained by Basque separatist group ETA during most of the year. Coming in a distant third in number of incidents was left-wing/anarchist attacks in Greece. At the bottom of the list were Estonia, Finland, Hungary, Latvia, Lithuania, Slovakia and Slovenia, who all reported neither investigations nor court proceedings related to terrorism in 2006, suggesting that they are the least affected by terrorism in the region.
