North Korea's specialist media 38 North says North Korea has no signs of operation at its Yongbyon nuclear facility.

38 North said, "There is no clear indication that commercial satellite images of the North Korean nuclear research center in Yongbyon show that they are operating at the 5-megawatt reactor and the experimental light-water reactor."

"We have not seen any movements in the Pumyeong nuclear test site," North said.
