The Sri Lankan navy destroyed two Tamil Tiger rebel naval boats during a fierce clash in the northern sea on Sunday, the military said. Fighting erupted when nearly 20 boats from the Tamil Tigers' sea wing headed toward the navy-guarded harbor in Point Pedro off the Jaffna peninsula, said Commander D.K.P. Dassanayake, a navy spokesman. "Two of their boats were destroyed in the battle so far," he said, adding that the navy suffered no casualties. Dassanayake said the battle was continuing.
