This book highlights contemporary problem faced by the world - terrorism. Terrorism is a very complex term to be defined because of the lack of clarity in the manifestation of terrorist acts, motives and their objectives. Terrorism is often referred to as an act of violence directed towards civilians and non-combatants in pursuit of political or ideological aim. Today, terrorism has become one of the biggest security challenges to the world community. It can threaten the dignity and security of human beings to a great extent; disturb peaceful existence and create fear in the minds of people and also jeopardize the very fundamental freedom and destabilize governments. Contemporary terrorism is hologrammatic: it thrives on fear emanated through violence and propagated by using communication technology. Contemporary terrorism has shaken the traditional concept of security. It has shifted the entire debate to a non-traditional security domain.
