Yonhap: North Korea may have 15 to 60 nuclear warheads

The agency, citing data from the American magazine Bulletin of the Atomic Scientists, suggests that as of September 2022, the DPRK had 

20-30 nuclear warheads suitable for medium-range missiles.

North Korea had 20 charges in June last year, according to data from the Stockholm Peace Research Institute.

Also, analysts from Japan report a large number of nuclear warheads in the DPRK.

On January 2, Kim Jong-un, accompanied by his daughter, inspected a warehouse with KN-23 missiles that can carry a tactical nuclear charge, as well as Hwaseong-12 medium-range ballistic missiles.
