In July 1983, there were wide spread attacks against Tamils in Sri Lanka. Many Tamils left the country, and many young people went to the training camps in India. The LTTE fought against the government. They had their own navy, the Sea Tigers, and air force. In July 1987 Prabhakaran started a group called the "Black Tigers". These were a group of male and female suicide bombers. Their explosive belts have been copied by groups in Palestine, Chechnya and Iraq. India sent 100,000 peace keeping soldiers to Sri Lanka in July 1987. The Indian government and the Sri Lankan government signed an agreement, but Prabhakaran did not like it because it did not create a separate Tamil country. The Indian soldiers were soon fighting against the LTTE.
