Government soldiers and Tamil Tiger rebels fought a series of battles across Sri Lanka's war-ravaged northern region, killing 26 rebels and one soldier, the military said Saturday. Fighting on the Indian Ocean island has escalated in recent weeks with government forces sweeping deep into rebel-held territory, capturing insurgent bases and threatening to overrun the Tamil Tigers' administrative capital at Kilinochchi. The latest infantry clashes took place Friday along the front lines in Vavuniya, Kilinochchi, Welioya and Jaffna districts, a military statement was quoted as saying by the Associated Press.
