A wave of fighting in Sri Lanka's civil war killed 25 Tamil Tiger rebels and five soldiers, Associated Press quoted the military as saying today. Military spokesman Brig. Udaya Nanayakkara said the worst fighting Saturday broke out when troops pushing toward the rebel stronghold of Kilinochchi battled with guerrillas in Akkarayankulam village. The fighting killed 12 insurgents and five soldiers, Nanayakkara said. Separate clashes in Jaffna, Vavuniya and Welioya killed another 13 rebels and wounded several soldiers, he said.
