Suicide attack
Suicide attacks include both Suicide terrorism—terrorism often defined as any action "intended to cause death or serious bodily harm to civilians or non-combatants" for the purpose of intimidation—and suicide attacks not targeting non-combatants. An alternative definition is provided by Jason Burke, a journalist who has lived among Islamic militants, and suggests that most define terrorism as 'the use or threat of serious violence' to advance some kind of 'cause', stressing that terrorism is a tactic. Academic Fred Halliday, has written that assigning the descriptor of 'terrorist' or 'terrorism' to the actions of a group is a tactic used by states to deny 'legitimacy' and 'rights to protest and rebel'.
Definitions of terrorism
In September 2002, the U.S. national security strategy defined terrorism as "premeditated, politically motivated violence against innocents." This definition did not exclude actions by the United States government and it was qualified some months later with "premeditated, politically motivated violence against noncombatant targets by subnational groups or clandestine agents".
