Fighting across Sri Lanka's embattled northern region left at least 18 Tamil Tigers and two soldiers dead, the defence ministry said Tuesday. Monday's fighting in the regions of Mannar and Vavuniya also wounded 10 Tiger rebels and 18 government troopers, the ministry said. However, the Liberation Tigers of Tamil Eelam (LTTE) said they killed 26 soldiers during Monday's clashes in the two areas. The rebels said 20 soldiers were also killed in ground battles in Mannar on Sunday.
