Supported by the ongoing politics of conflict in Sri Lanka, politicised Tamil youth in the north and east started to form militant groups. These groups developed independently of the Colombo Tamil leadership, and in the end rejected and annihilated them. The most prominent of these groups was the TNT, which changed its name to the Liberation Tigers of Tamil Eelam, or the LTTE, in 1976. The LTTE initially carried out a campaign of violence against the state, particularly targeting policemen and also moderate Tamil politicians who attempted a dialogue with the government. Their first major operation was the assassination of the mayor of Jaffna, Alfred Duraiappah, in 1975 by Prabhakaran.
