COLOMBO (AFP) - Sri Lanka celebrated victory over the Tamil Tigers with a national holiday on Wednesday as the army hunted down fugitive rebels, shooting dead eight thought to have escaped from the final battle. Hundreds of troops were deployed in the Muliyawaikal area where the corpse of Tiger leader Velupillai Prabhakaran was found after the fighting ended with a showdown in the jungle on Monday, officials said. They are doing clearing operations, defence spokesman Lakshman Hulugalle said as more bodies were gathered for identification. The eight rebels were shot in two incidents more than 130km south of where the Tigers made their last stand in the far northeast, the army said. The killings were the first since the government claimed victory over the Liberation Tigers of Tamil Eelam (LTTE), and police stepped up security across the island to guard against revenge attacks from surviving guerrillas.
