According to Reuters, independent observers of the United Nations said that “work at the (Bungi-ri) nuclear test site paves the way for additional tests to develop nuclear weapons.”
“(North) Korea has continued to develop its fissile material production capacity at the Yongbyon site,” the observers wrote.
Yongbyon is North Korea’s main nuclear facility, and operates its first nuclear reactors.
The United States has long warned that North Korea was preparing to conduct a seventh nuclear test, vowing to impose more sanctions on Pyongyang.
Observers also said investigations showed that Pyongyang was responsible for stealing hundreds of millions of dollars worth of cryptocurrency in one major hack to fund its nuclear and missile programs.
