Sri Lankan jets bombed a Tamil Tiger naval base in the north of the island on Thursday in a third consecutive day of air strikes despite United Nations calls for an end to the fighting, Reuters reported. The military said the Tiger base in the rebel-controlled Mullaittivu area had been destroyed in the bombardment, which followed a similar raid in the east on Wednesday. It has vowed to dislodge the Liberation Tigers of Tamil Eelam from their eastern stronghold, accusing the rebels of firing on them despite a 2002 ceasefire that international monitors say now exists only on paper.
