Japan has detected radio signals which suggest North Korea may be preparing for another ballistic missile launch, its government said.Kim Jong-un has fired missiles at a rate of two or three a month since April but launches paused in September after Pyongyang fired a rocket that passed over Japan’s northern Hokkaido islandSatellite images have not shown fresh activity and such radio signals are not unusual, a government source told Reuters."This is not enough to determine (if a launch is likely soon)," the source said. The Japanese government is on alert after catching such radio signals, suggesting a launch could come in a few days, Kyodo news agency reported.
The report also said the signals might be related to winter military training by the North Korean army. Intelligence officials of the United States, South Korea and Japan recently detected signs of a possible missile launch and have been on higher alert, Yonhap news agency reported.Two US government sources said that while they were not immediately familiar with recent intelligence, the US government would not be surprised a North Korean nuclear test were to take place in the very near future. Other US intelligence officials noted North Korea has previously sent deliberately misleading signs of preparations for missile and nuclear tests, in part to mask real preparations, and in part to test US and allied intelligence on its activities.
