In northeastern Sri Lanka, thousands of people have been left homeless following military strikes on suspected Tamil Tiger positions. Local authorities said more than 40,000 people have been displaced. The strikes have killed at least 15 people, with many more believed to be trapped beneath the bombed-out rubble. The bombings come after a suicide bombing on an army motorcade that killed eight people Tuesday. A top military official was among those wounded in the attack. The Tamil Tigers have denied responsibility for that bombing.
