KYIV, Ukraine (AP) A video purporting to show dozens of North Korean recruits lining up to collect Russian military fatigues has been released by Ukrainian officials, who say it shows the introduction of troops sent by Pyongyang into the conflict.

The video, published by Ukraines Center for Strategic Communications and Information Security, which operates under the Culture and Information Ministry, allegedly shows North Korean soldiers standing in line to pick up bags, clothes and other apparel from Russian servicemen. The Associated Press couldnt verify the video independently.

We received this video from our own sources. We cannot provide additional verification from the sources who provided it to us due to security concerns, said Ihor Solovey, the head of the center.

The video clearly shows North Korean citizens being given Russian uniforms under the direction of the Russian military, he said. For Ukraine, this video is important because it is the first video evidence that shows North Korea participating in the war on the side of Russia. Now not only with weapons and shells but also with personnel.

The center claims the footage was shot by a Russian soldier in recent days. It didnt say how the footage was obtained. The location is unknown.
