Terror attacks occur in the form of a terror strike through the use of explosives, guns or chemical and biological weapons. Terrorists also hijack planes and destroy public infrastructure such as railway track and bridges to cause massive devastation. Most of the attacks are brought about by misdirected elements who think that social,
political or religious goals can be achieved by killing people.
For example :
1. The attack on the World Trade Center in the US on 11 September 2001, when terrorists hijacked planes to spread terror, resulting in nearly 3000 deaths.
2. The terror attack on Parliament in India on 13 December 2001. 3. The Mumbai attacks on 26 November 2008.
