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'.
Terrorism
There is no commonly accepted definition of "terrorism". Being a charged term, with the connotation of something "morally wrong", it is often used, both by governments and non-state groups, to abuse or denounce opposing groups. Broad categories of political organisations have been claimed to have been involved in terrorism to further their objectives, including right-wing and left-wing political organisations, nationalist groups, religious groups, revolutionaries and ruling governments. Terrorism-related legislation has been adopted in various states, regarding "terrorism" as a crime. There is no universal agreement as to whether or not "terrorism", in some definition, should be regarded as a war crime.
