Sri Lankan air force jets bombed two Tamil Tiger rebel locations Saturday in the island's north, where government troops are trying to capture the insurgents' de facto capital, the military said. Fighter jets targeted a rebel stronghold and a mortar launching position in the Paranthan area north of the rebel headquarters at Kilinochchi, the military said in a statement. Pilots confirmed that the raids were successful, it said, without giving casualty details. Rebel officials could not be contacted for comment because most communication lines to rebel territory have been severed. The military has increased its air strikes on northern targets in recent weeks in a bid to soften rebel resistance to soldiers trying to enter Kilinochchi.
