His handling of the country's civil war was less successful. In the north, the Liberation Tigers of Tamil Eelam were facing off against the Indian Peace-Keeping Force the Indian presence on the island was unpopular, and Premadasa requested India to pull out its troops. In order to force the IPKF to leave the island, he authorized a clandestine operation to supply arms to LTTE to fight the Tamil National Army formed by the IPKF, a collusion that came to light in the report published by the Sri Lankan Presidential Commission to inquire into the 1992 assassination of Lieutenant General Denzil Kobbekaduwa. While the IPKF was recalled by New Delhi in 1990, the government's war with the LTTE resumed, beginning Eelam War II, which ended in a stalemate five years later. The 1990 massacre of Sri Lankan Police officers, which occurred after the policemen were asked to surrender to the LTTE in Batticaloa at Premadasa's request, was later established to have been performed with the same weapons he had supplied them.
