Sri Lankan troops killed around 30 Tamil Tigers in a clash overnight in a jungle in the island's restive east, the military said on Wednesday, hours after the navy said it had killed around 40 insurgents in a sea battle. The military said soldiers had captured a rebel bunker line during the fight in a swathe of landlocked jungle called Thoppigala, where Tiger fighters are still entrenched after the fall of their eastern stronghold earlier this year.
