Terrorists have different goals and objectives. The nature of terrorism varies in accordancewith the objectives. The commonly distinguished types of terrorism are:
Ethno-nationalist terrorism is defined as intentional violence inflicted by a sub-national ethnic group in order to further its cause. They are either focused on the establishment of a separate state or on the elevation of one ethnic group over others. Tamil nationalist organisations in Sri Lanka and insurgent groups in the North-east are two examples.
These terrorists are motivated wholly or partially by religious ideals, who consider violence as their divine duty or a holy act. It gives them different ways of legitimization and justification when compared with other terrorist groups, and these unique factors make religious terrorism more dangerous and more brutal in committing heinous acts. For example, ISIS.
In some sections of the country, the naxal movement (left-wing extremism) has been acause of violence. Internally, these militants are launching assaults against the state. It isregarded as the most serious security concern. Their modus operandi is to cut off several tribalregions from the national grid because of these radical movements.
Right-wing terrorism either wants to maintain the status quo or return to a specific period inhistory that they believe should be preserved. These right-wing organisations can also take onethnic/racist/religious overtones. Right-wing terrorists want to overthrow the regime and install a hyper-nationalist or fascist regime in its place. Fascist anarchists, thugs, youth supporters, and academics are among those who believe that the government must send foreigners out of the country to safeguard the country’s native population. They may function as a pressure organisation, using violence or the threat of violence to compel the government to acquire territory or intervene in the affairs of a neighbouring country, with the Nazi party of Germany serving as the best example.
Cyber terrorism is an act of terrorism which uses the internet to disrupt large scale computer networks using computer viruses and other means against computers, networks and the information kept therein to intimidate a state and its people. Thus, cyber-terrorism is the most advanced means of terrorist strategy evolved parallel with the advancement in information and communication technologies. In cyber-terrorism, the use of information technology would drastically disrupt internet-connected services. For example, a cyber-attack on the critical infrastructure of a nation.
Bio-Terrorism uses biological weapons that are inflicted naturally or in a modified biological manner to create large-scale death and harm to human beings. For a political or other cause, biological toxins are deployed to harm and intimidate innocent victims. For example, the use of Sarin gas in Syria.
Nuclear terrorism is defined as any act of terrorism in which a person or group of people detonates a nuclear weapon. Terrorists can use nuclear material in various ways, which is referred to as nuclear terrorism. It includes attacks on nuclear plants, the preparation or purchase of nuclear weapons, and the development of a means to discharge nuclear weapons. Nuclear arms and radioactive materials on the black market are a global danger, as is the possibility of a militant group detonating a compact, unsophisticated nuclear weapon in a big population, resulting in severe loss of life and property
