Seoul, South Korea — North Korea said Monday it fired a test satellite in an important final-stage test for the development of its first spy satellite, a key military capability coveted by its leader Kim Jong Un along with other high-tech weapons systems.The North's official Korean Central News Agency also released low-resolution, black-and-white photos showing a space view of the South Korean capital and Incheon, a city just west of Seoul, in an apparent attempt to show the North is pushing to acquire a surveillance tool to monitor its rival.Many foreign experts say both satellites were tasked with spying on its rivals though there has been no evidence that either satellite has ever relayed any imagery back to North Korea.According to North Korea's state media, one of the cameras tested Sunday has a 20-meter resolution, which Lee, the expert, said can only recognize relatively big targets such as warships sailing on the ocean and military installations in South Korea.It also legislated a law authorizing the preemptive use of nuclear weapons on a broad range of scenarios, causing security jitters in South Korea and elsewhere."
