A source familiar with the issue told Reuters that the United States is aware of the North Korean deployment, but declined to elaborate. Russia expects the deployment to involve 120 North Korean ballistic missiles and six launchers, he said. The deployment described by Cherniak appears to coincide with Russia last week firing its first two ⁠North Korean missiles at Ukraine since last August.
