There are a number of typologies of criminal behaviour that have been associated with terrorism. These will be presented in the following sections with the support of relevant case studies. The typologies have been chosen for analysis based on existing literature and UN Security Council resolution 2195 (2014), which expresses concern:

The crime-terrorism linkages are examined as they play out through the following activities:
Each typology contains some key facts and at least one case study.
