The objective of this report is to outline the terrorism situation in the European Union over the last twelve months and analyse the trends established. The report is intended to inform the European Parliament on the phenomenon of terrorism targeting the Member States. This is an open report based on contributions from the Member States, complemented from open source material, where necessary. An overview of terrorist activities is offered in two parts, the first of which relates to activities carried out by various indigenous groups within the European Union Member States, while the second part focuses on international terrorist activities affecting the European Union (EU). For the first time, the content of this report reflects contributions from new Member States.
