North Korea is apparently moving to sell millions of rockets and artillery shells — many of them likely from its old stock — to its Cold War ally Russia.
Russia has called a U.S. intelligence report on the purchasing plan "fake." But U.S. officials say it shows Russia's desperation with the war in Ukraine and that Moscow could buy additional military hardware from North Korea.
The ammunitions North Korea reportedly intends to sell to Moscow are likely copies of Soviet-era weapons that can fit Russian launchers. But there are still questions over the quality of the supplies and how much they could actually help the Russian military.
