Heavy fighting in Sri Lanka's intensifying civil war killed 20 Tamil Tiger rebels and one soldier, the military said Monday. In new fighting Sunday, troops captured part of a strategic road in the Kilinochchi district after a seven-hour battle that killed seven rebels and one soldier, the military said in a statement. Attacks on rebel bunkers and other scattered fighting killed 11 rebels in the Welioya, Jaffna and Vavuniya districts, it said. Another two rebels were killed in a brief firefight in Ampara in the east, the military was quoted as saying by the Associated Press.
