Over 14,000 North Korean soldiers are currently fighting for Russia against Ukraine alongside mercenaries from 136 countries, including South Korea, according to Kyiv’s military intelligence.

Dmytro Usov, a Ukraine’s Defense Intelligence representative and Secretary of the Coordination Headquarters for the Treatment of Prisoners of War, announced the figures at a Wednesday presentation of a new report about Russia’s “exploitation” of foreign fighters in the ongoing conflict.

Of the roughly 14,000 to 14,100 DPRK soldiers stationed in Russia, 9,500 were deployed as active combatants as of early this year, according to Usov’s presentation about Russia’s recruitment of foreign nationals.
