A pro-rebel Web site reports that the Tamil Tiger insurgents have killed 43 Sri Lankan soldiers in a single fierce clash in the island's north. Pro-rebel TamilNet Web site quotes unnamed rebel officials as saying that the soldiers were killed Sunday in a clash in Nalloor village of the rebel-held Kilinochchi district, according to a report of Associated Press. Lakshman Hulugalle, the chief of the government's security information center, declined to comment, saying that the government would not react to pro-rebel news reports. Independent verification of the report is not possible because journalists are barred from the war zone.
