Counter terrorism and radicalisation

The European Union aims to be an area of freedom, security and justice, without internal frontiers. Europeans should feel confident that wherever they move within the EU, their freedom and their security are well protected.

One of the main threats to those aims is terrorism. A menace that does not recognise borders and affects countries and people irrespective of their geographical location. 

Individuals and groups should not advance their political aims by using terror, challenge the democratic values of our societies and put in jeopardy the rights and freedoms of our citizens, especially by indiscriminately targeting people. Acts of terrorism are criminal and unjustifiable and must be treated as such under all circumstances.

Radicalisation prevention

Prevention of radicalisation includes removing terrorist content online, preventing radicalisation of prison inmates, together with rehabilitation and reintegration, and helping victims of terrorism.


The European Commission supports EU countries in enhancing the protection of citizens and critical infrastructures, especially public spaces, against terrorist threats.

Fight against financing of terrorism

As terrorists and their supporters constantly modify their ways to collect, move and gain access to funds, the EU needs to adapt its instruments and measures to deny them resources.

2020 Counter-Terrorism Agenda for the EU

On 9 December 2020, the Commission adopted a new Counter-Terrorism Agenda for the EU, setting out a way forward for actions to counter terrorism at EU level, looking to better anticipate, prevent, protect and respond to terrorist threats.

The Counter-Terrorism Agenda is one of the deliverables of the way forward on internal security, a core component of the Security Union Strategy adopted by the Commission in July 2020. 

  • Anticipate: identifying vulnerabilities, building capacity where most needed 
  • Prevent: tackling radicalisation at all levels
  • Protect: increasing security, denying terrorist the means to act, reinforcing external borders
  • Respond: minimising impact, allowing prosecution, increasing support to victims

    Directive on combating terrorism

    On 15 March 2017, the EU adopted the Directive on combating terrorism. The Directive reinforces the legal framework to more comprehensively cover conducts related to terrorism. All EU countries have to ensure that they criminalise conduct such as training and travelling for terrorism, as well as terrorist financing. These harmonised definitions of terrorist offences serve as a benchmark for cooperation and information exchange between national authorities.

Within Europol, the EU Agency for law enforcement cooperation, the ECTC pools specialised resources, expertise and information on foreign terrorist fighters, explosives, firearms, financial intelligence and online propaganda to support Member States' law enforcement counterterrorism units.
