KYIV, Ukraine — 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 Ukraine’s 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 couldn’t 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. — The Associated Press
