As many as 100,000 people may have been killed in a civil war that raged for a quarter-century in Sri Lanka. The Tamil Tiger rebels, known as the LTTE, were defeated fighting for an independent homeland for ethnic Tamils. The rebel group said Tamils have been discriminated and marginalized by the government, which is dominated by a Sinhalese majority. The conflict escalated in January, when the Sri Lankan government pulled out of a cease-fire with the Tamil Tigers. The LTTE, considered a terrorist organization by Sri Lanka, the U.S. and many other countries, waged a campaign of suicide bombings and assassinations as part of its violent quest for a Tamil homeland.
