Cherniak warned that their battlefield experience will be transferred back to North Korea and shared with other units, reinforcing Pyongyang’s capabilities and contributing to instability in the Asia-Pacific region.

Russia has violated a
partial ceasefire
covering energy infrastructure more than 30 times since it was agreed in March, targeting critical infrastructure across Ukraine, a Ukrainian Foreign Ministry spokesperson said on April 16.

and a power transmission line in
