- An unnamed intelligence source said a movement of missiles was detected
- The missiles were being moved away from North Korea's missile facility
- The missiles could be of intermediate range or the intercontinental ones
The report cited an unnamed intelligence source saying South Korean and US intelligence officials detected missiles being transported away from North Korea's Missile Research and Development Facility at Sanum-dong in the northern part of Pyongyang.
The report did not say when or where they had been moved.
The missiles could be either intermediate range Hwasong-12 or intercontinental ballistic Hwasong-14 missiles, according to the report, though the missile facility at Sanum-dong has been dedicated to the production of intercontinental ballistic missiles.
A source from South Korea's defense ministry said he could not confirm details of the report or whether there has been any unusual activities in the area mentioned.
South Korean officials have voiced concerns that North Korea could conduct more provocative acts near the anniversary of the founding of its communist party on October 10, or possibly when China holds its Communist Party Congress on October 18.
Amid heightened tensions on the Korean Peninsula, South Korea and US forces recently held their first joint short range air defense training exercise in South Korea, according to a statement released by the US Pacific Command on Friday.
The statement did not give the date of the exercise, but said the next exercise is scheduled to take place over the next few months as the two forces become more familiar with each other's capabilities.
