The first country to ban the LTTE was its brief one-time ally, India. The Indian change of policy came gradually, starting with the IPKF-LTTE conflict, and culminating with the assassination of Rajiv Gandhi. India opposes the new state Tamil Eelam that LTTE wants to establish, saying that it would lead to Tamil Nadu's separation from India, despite the leaders and common populace of Tamil Nadu considering themselves Indian. Sri Lanka itself lifted the ban on the LTTE before signing the ceasefire agreement in 2002. This was a prerequisite set by the LTTE for the signing of the agreement. The Indian Government extended the ban on LTTE considering their strong anti-India posture and threat to the security of Indian nationals.
