COLOMBO - Sri Lankan air force jets bombed and destroyed a Tamil Tiger naval base near the northeastern district of Mullaittivu, the military said on Monday, but had no immediate details of any casualties.The attack at Chundikkulam came a day after the navy sank two large ships off the east coast it said were transporting arms for the Tigers, and as the government pushed on with a declared plan to destroy the rebels’ military machine. ‘We have taken selected targets,’ said air force spokesman Group Captain Ajantha de Silva. ‘This is a Sea Tiger base we have identified. We believe it is fully destroyed.’
