This comes after the United States said North Korea appears to be supplying Russia with artillery shells for its war in Ukraine.

The White House National Security spokesperson, John Kirby, said last week the United States has information that indicates North Korea is covertly supplying Russia with a "significant" number of artillery shells.

Kirby said North Korea was attempting to obscure the shipments by funnelling them through countries in the Middle East and North Africa and that Washington was monitoring to see whether the shipments were received.

A North Korean defence ministry official called the allegations a rumour and said Pyongyang has "never had ‘arms dealings’ with Russia" and has "no plan to do so in the future."

"We regard such moves of the US as part of its hostile attempt to tarnish the image of the DPRK in the international arena by invoking the illegal 'sanctions resolution' of the (UN Security Council) against the DPRK," the official said in a statement carried by the KCNA, referring to the North by the initials of its official name.

Any arms aid would be a further sign of deepening ties between Moscow and Pyongyang as Russia’s isolation over its war in Ukraine has grown.
