There are indications of the North Korean production of enriched uranium at a Yongbyon facility, IAEA Director General Rafael Grossi said on Monday.

There were indications consistent with the production of enriched uranium at the enrichment centrifuge facility in Yongbyon. It is also likely that North Korea has continued construction work inside the experimental light water reactor. However, there is still no work at the 5-megawatt nuclear reactor and radiochemical laboratory, Grossi said, speaking to the agency's board of governors.

He added that the North Korean nuclear activities continue to cause serious concern, the country's nuclear program violates the relevant UN Security Council resolutions. Grossi again called on North Korea to cooperate with the IAEA to resolve all issues, especially those that arose in the absence of agency inspectors in the country.
