Pyongyang has refuted Washington's claims about Russian missile deliveries. In a statement released by the official Korean Central News Agency, a senior North Korean official denied the accusations, warning that the U.S. would face a really undesirable result if it persisted in spreading rumors.

Attempting to tarnish (North Korea's) image by fabricating non-existent facts is a serious provocation that should not be allowed to go unchecked, said Kwon Jong Gun, director general of the Foreign Ministry's Department of U.S. Affairs.

He also called it a foolish attempt (by the U.S.) to justify its arms deliveries to Ukraine.

According to him, the U.S. decision to send tanks to Ukraine is a criminal act against humanity aimed at perpetuating an unstable international situation.
