North Korea War Training Shown Off In Video

01 April 2013 North Korea has released footage of troops in live-fire training exercises - with targets including a cartoon-like drawing of a US soldier. The video from state TV emerged days after the country warned it was in a "state of war" with the South. It is not clear when the footage was filmed, but it comes after Pyongyang voiced anger over joint US-South Korean military drills south of the border. On Sunday, the North's leader Kim Jong-Un vowed to bolster its nuclear capability and described atomic weapons as "a national treasure".
