North Korea seemed to stop moving vehicles suspected to be mobile launchers for its medium-range missiles over the past two days, a government source said Saturday, in a sign that Pyongyang\'s missile launch may not be imminent.According to intelligence sources, the North had moved two Musudan intermediate missiles, which had been concealed in a shed in the eastern port city of Wonsan, in and out of the facility earlier this week in an apparent bid to interfere with Seoul\'s intelligence monitoring.
