In Sri Lanka what type of war occured that gives evidence of religious tension

The Sri Lankan Civil War (1983-2009) was a conflict between the Sinhalese Buddhist majority and the Tamil Hindu minority. The conflict was mainly based on ethnic and religious tensions, with the Tamil Tigers, a separatist militant organization fighting for an independent Tamil state in the north and east of the country. The war resulted in significant loss of life and displacement of populations, as well as widespread human rights abuses committed by both sides.
