Importantly however, the Tamil groups, notably the Liberation Tigers of Tamil Eelam (LTTE) (which at the time was one of the strongest Tamil forces), had not been made party to the talks and initially agreed to surrender their arms to the Indian Peace Keeping Force (IPKF) only reluctantly. Within a few months however, this flared into an active confrontation. The LTTE declared their intent to continue the armed struggle for an independent Tamil Eelam and refused to disarm. The IPKF found itself engaged in a bloody police action against the LTTE. Further complicating the return to peace was a burgeoning Sinhalese insurgency in the south.
Sri Lanka, from the early part of the 1980s, was facing an increasingly violent ethnic strife. The origins of this conflict can be traced to the independence of the island from Britain in 1948. At the time, a Sinhala majority government was instituted which passed legislation that were deemed discriminatory against the substantial Tamil minority population. In the 1970s, two major Tamil parties united to form the Tamil United Liberation Front (TULF) that started agitation for a separate state of Tamil Eelam within the system in a federal structure in the north and eastern Sri Lanka that would grant the Tamils greater autonomy. However, enactment of the sixth amendment of the Sri Lankan Constitution in August 1983 classified all separatist movements as unconstitutional, effectively rendering the TULF ineffective. Outside the TULF, however, factions advocating more radical and militant courses of action soon emerged, and the ethnic divisions started flaring into a violent civil war.
