Russia has begun deploying a North Korean missile unit in its war theater against Ukraine, according to a Reuters report citing a senior Ukrainian intelligence official. The reported deployment adds to concerns about North Korea’s military support for Moscow’s invasion.

The official said the unit was active in the conflict, although the available report did not provide further operational details. Ukraine’s intelligence assessment suggests Russian forces may be seeking to use additional foreign-supplied capabilities in the war.

The report also indicated that the deployment could exploit vulnerabilities facing Ukraine. Any expansion of North Korean military involvement would further highlight the international dimensions of Russia’s war against its neighbor.
