North Korea appears to have restarted its Yongbyon nuclear reactor, the UN atomic agency has said in a report.
Plutonium, which is used for nuclear weapons, is believed to be produced at the reactor's complex.
The International Atomic Energy Agency (IAEA) was expelled by Pyongyang in 2009 but relies on satellite imagery to carry out assessments.
The watchdog said the reactor has been discharging cooling water since July, suggesting it is operational.
Yongbyon, a nuclear complex with a 5-megawatt reactor, is at the heart of North Korea's nuclear programme.
This was the first sign of operational activity at the reactor since December 2018, months after US President Donald Trump met Kim Jong-un in Singapore, according to the IAEA.
