NKorea: We have "guns and bayonets" aimed at SKorea

North Korea warned Monday that it does not engage in "empty talk" and has "guns and bayonets" aimed at its southern neighbor, heightening tensions surrounding its threat to take military action to counter what it calls South Korean plans to invade. North Korea's military accused South Korean President Lee Myung-bak on Saturday of plotting an invasion of the North and warned of strong military steps in retaliation and "an all-out confrontational posture." South Korea denied it was planning to invade and put its military on alert. South Korea said Monday it had detected no unusual moves by the North's military, and Unification Ministry spokesman Kim Ho-nyeon said Seoul will cope with the situation in a "calm" manner.
