A special North Korean train which transported a long-range rocket or intercontinental ballistic missile to a launch site in Tongchang-ri, North Pyongan Province in May recently moved from a missile research center in Sanum-dong, Pyongyang to another launch site in Musudan-ri, North Hamgyong Province, a South Korean government source said Tuesday.South Korean and U.S. authorities believe the North may have transported a second intercontinental missile to the launch site. The North launched a long-range rocket from Musudan-ri on April 5, which had also been transported by special train.
Seoul and Washington are wondering whether the North will launch two long-range missiles from both launch sites at the same time or whether the train is just a smokescreen to confuse watchers.
North Korea has threatened to launch another missile in protest against UN sanctions over its nuclear test. It apparently has three to four intercontinental ballistic missiles, and may be keeping one or two more at the research center in Sanum-dong.
