Signs of continued operation of N. Korea's Yonbyong and Kangson uranium enrichment facilities: IAEA

The chief of the UN's nuclear watchdog said Monday that there are signs North Korea is continuing activities at uranium enrichment facilities in two locations.

According to the International Atomic Energy Agency Director General Rafael Grossi, the uranium enrichment plants in Kangson and Yongbyon have been operating, which he called a "clear" breach of UN Security Council resolutions.

Grossi added that there are also indications that the light water reactor at Yongbyon continues to operate.

The assessment comes as North Korean leader Kim Jong-un was said to have toured a nuclear material production base and a nuclear weapons institute in January.
