Number of terrorism attacks in total: 11,283.
Terrorism is the systematic use of terror, especially as a means of coercion. In the international community, however, terrorism has no universally agreed, legally binding, criminal law definition. Common definitions of terrorism refer only to those violent acts which are intended to create fear (terror), are perpetrated for a religious, political or ideological goal, and deliberately target or disregard the safety of non-combatants (civilians).
