There are several forms of terrorist organizations in modern history. One of the most interesting types of terrorist organizations is ethno-nationalist/separatist terrorist groups. These types of terrorist groups include organizations such as Fatah, IRA, PKK and Tamil Tigers. Ethno-nationalist/separatist terrorism is “the use of terrorism by a substate against an ethnic or national group to alter its access to state power” (Kilroy, 2008, p. 180). Groups of this nature are unlike any other type of terrorist group in that they most often have a support base; these groups generally have a historical connection. The strength of ethno-nationalist/separatist terrorism is that it attracts others via ethnicity, which facilitates recruitment, integration and the use of violence. One organization to bring up when discussing this topic is the Modern Tamil Tigers. The Sri Lanka Tamil Tigers are structured with a hierarchical state that was formed in Sri Lanka during the year 1975. In the mid-1900s, Tamils ​​became targets of riots. and began to call for an organization that would protect their rights; this group vowed to form its own separate state. Since their creation, they have continued to try by all means to separate themselves from the country. The Tamil Tigers, like other terrorist groups, have attacked public buildings and transportation throughout the region. The Tigers also use tactics similar to other terrorist categories such as religious and ideological organizations by carrying out attacks with female suicide bombers and recruiting younger children; As the tigers developed, so did their tactics, culminating in the creation of the suicide vest. So far in their history, the LTTE has... paper... and does not have to worry about interference from the Sri Lankan government. ReferenceBishnoi, B. (nd).
