South Korea raises military alert status

South Korea has raised its military alert status, with the North, which is reportedly getting ready to launch a mid-range missile. Some call it psychological warfare but no one is taking any chances, with neighbouring Japan deploying interceptor missiles in and around Tokyo. And American military commanders say they too are ready for any North Korean aggression. Al Jazeera's Marga Ortigas reports from Paju, near South Korea's border with the North.
