North Korea is believed to possess up to two tonnes of highly enriched uranium, South Korea’s unification minister said Thursday.

“Intelligence agencies estimate Pyongyang’s stockpile of highly enriched uranium – more than 90 per cent pure – at up to 2,000 kilogrammes,” South Korea’s unification minister Chung Dong-young told reporters.

“Even at this very hour, North Korea’s uranium centrifuges are operating at four sites,” he added.
