This informative text analyses the deficiencies of the existing counter-terrorism legal framework and examines whether the Statute of the International Criminal Court (ICC) could provide an alternative and viable solution. The major objective of the work is to assess whether acts usually referred to as 'terrorism' in the common language, present the elements of war crimes, crimes against humanity, genocide and aggression, thereby falling within the jurisdiction of the ICC. Amongst the highlights are a comparison between the definitions provided by existing international law and the recently adopted ICC Statute; an analysis of the strengths and weaknesses of the principal international anti-terrorism conventions; and whether so-called acts of terrorism may constitute war crimes, crimes against humanity, genocide, and aggression, both under traditional international law and the ICC Statute.
