IAEA flags N Korea nuke activity

PYONGYANG:

North Korea is showing a "very serious increase" in its ability to produce atomic weapons, the head of the UN nuclear watchdog said on Wednesday on a visit to Seoul.

The diplomatically isolated north is believed to operate multiple facilities for enriching uranium, a key step in making nuclear warheads, South Korea's spy agency has said.

They include one at the Yongbyon nuclear site, which Pyongyang purportedly decommissioned after talks but later reactivated in 2021.

"In our periodic assessments, we have been able to confirm that there's a rapid increase in the operations" of the Yongbyon reactor, International Atomic Energy Agency (IAEA) chief Rafael Grossi told reporters in Seoul.

The agency also observed a rise in operations at Yongbyon's reprocessing unit and light-water reactor, as well as the activation of other facilities, Grossi said.

"All that points to a very serious increase in the capabilities of (the) Democratic People's Republic of Korea (DPRK) in the area of nuclear weapons production, which is estimated at a few dozen warheads," he said, using North Korea's official name.

North Korea, which conducted its first nuclear test in 2006, is under rafts of UN sanctions for its banned weapons programmes.
