N. Korea Warns of 'Unpredictable Military Conflicts'

The rare threat came as North Korea was apparently gearing up to test-fire a long-range missile believed capable of reaching U.S. territory. Pyongyang has also stepped up its war of rhetoric against the South over Seoul's tough stance toward its communist neighbor.North Korea's military said U.S. troops advanced as close as 100 feet from the Military Demarcation Line in the western border and took pictures of a North Korean military post last month. It also said more than 60 U.S. patrols approached to within 330 feet of the boundary this year.
