ABSTRACT
This chapter focuses on international practice relating to the repression of international terrorism, underlining how certain cases reflect the dual approach to collective guarantees with regard to the general powers exercised by states in combating terrorism in the common interest. It argues that the protection of global interests and rights offers a legal basis for extra-territorial coercion and jurisdictional powers that can be exercised by states on an exceptional basis, beyond the typical limits of their jurisdiction. The chapter addresses situations in which states allegedly violate the sovereignty of another state in an effort to rescue individual victims of terrorism or to arrest those responsible for terrorist acts. Authorization is often granted by a state in whose territory a hijacked aircraft landed to allow the state with which the aircraft is registered, to carry out a military intervention in order to bring the hijacking to an end and to free the hostages.
