U.S. Ally Panics After North Korea's Artillery Shelling; China Tells Kim Jong-un To 'Stay Calm'

North Korea conducted artillery shelling at the border with South today morning. The firing prompted South Korea to tell residents of Yeonpyeong Island to evacuate to bomb shelters. Seoul then warned Pyongyang and conducted retaliatory military drills with the U.S. North Korea's action did not cause any damage or casualties on the South's side but it came as Kim Jong-un toured a ICBM launcher factory with his daughter. The North Korean leader called for expanded production of missile launchers in preparation for a "military showdown" with South Korea and the U.S. there. Watch for more details.
