A South Korean government source said Saturday that North Korea seemed to stop moving vehicles suspected to be mobile launchers for its medium-range missiles over the past two days, 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.Four or five vehicles, suspected of being so-called transporter erector launchers (TEL), were also previously moving around in South Hamgyeong Province.But a government source said that since Thursday the North has stopped moving the mobile launchers, whose timing comes on the heels of a dialogue proposal by South Korea and the U.S.“There are no signs that the TELs have been moved in and out of the facility since Thursday or that missile launches are imminent,” the government source said. “Situations surrounding the missile launch have not changed.”Geopolitical risks have heightened on the Korean Peninsula amid speculation that North Korea is poised to launch its medium-range ballistic missile, which is believed to be capable of flying as far as the U.S. territory of Guam in the Pacific Ocean.It is likely that Pyongyang fires missiles on April 15, which marks the celebration of the birth of former North Korean leader “Kim Il Sung.”
