North Korea is believed to have moved two sets of long-range Taepodong-2 missile to a launch site in Musudanri, North Hamgyeong Province, South Korea’s National Defense Minister Yoon Kwang-ung said Friday.

Yoon received intelligence suggesting the existence of another Taepodong-2 missile at the Musudanri base, however it has yet to be verified.

One Taepodong-2 missile had launched from the site on July fifth and failed. It will take some time for the North to launch another one.
