Europol is a unique organisation, offering EU Member States access to its expertise and information capabilities in support to their efforts in fighting serious organised crime and terrorism. The EU Terrorism Situation and Trend Report (TESAT)is one result of the excellent collaboration that exists between Europol and Member States. This public document, published annually, presents facts and figures regarding terrorism in the EU for the benefit of law enforcement officials, policy makers and the general public and also seeks to identify developing trends in terrorism. This and previous editions of the TE-SAT reports are available on Europol’s website., Acts of terrorism in 2013 caused the death of seven people in the European Union (EU). This, along with the sustained number of Europeans taken hostage by groups or individuals linked to religiously inspired terrorism, demonstrates the continuing terrorist threat posed to the security of citizens and interests of the European Union. The presence of potential or experienced terrorists in the EU, as evidenced by the number of arrests in 2013 for offences related to terrorism, is also a serious cause for concern.,
