Russia allegedly used North Korean-supplied ballistic missiles in its recent strikes against cities throughout Ukraine.
A Ukrainian police official stated that two out of the five missiles that struck the city of Kharkiv originated from North Korea.
Explosive Ordnance Disposal teams recovered materials from the explosions, determining that the projectiles were KN-23 (Hwasong 11GA) Short Range Ballistic Missiles.
The United States previously said in mid-January that the Kremlin used missiles of North Korean origin during strikes on December 30th and January 2nd.
Although the allegations are not 100% confirmed, evidence such as missile debris points to the missiles being KN-23s, which is becoming a concern for both the United States and Europe regarding arms trade between North Korea and Russia.
