COLOMBO, Jan 22: Tamil Tiger rebels shot dead two soldiers and two policemen in Sri Lanka's embattled northeast as security forces dug in at a town seized from the guerillas, the defence ministry said on Monday.

The two soldiers were shot on Sunday night in the eastern district of Batticaloa, where troops captured the main rebel bastion of Vakarai town on Friday, the ministry said, adding a Tiger rebel was also killed.

The ministry said the two policemen were shot late on Sunday in the northern district of Vavuniya. Five civilians were shot dead by unidentified gunmen in the same region, local police said. They said the latest victim, a top official at the local transport authority, was shot dead as he rode a motorcycle home with his wife on Monday evening.

Six civilians were gunned down in the same region last week, despite a heavy presence of police and troops.

The ground troops who captured Vakarai in the island's east were clearing the area of mines and booby-traps for a second straight day on Monday, military officials said.

Earlier Sunday, the military said it had found 37 dead Liberation Tigers of Tamil Eelam (LTTE) rebels near Vakarai, taking the toll from weeks of fighting to above 430.

Vakarai originally housed about 35,000 civilians, but an estimated 20,000 have fled the coastal area in recent weeks. The others started fleeing to government-controlled areas from Friday.—AFP
