SEOUL: North Korea on Tuesday accused the United States of cooking up a 'plot-breeding story' on its alleged arms transfer to Russia, arguing it has never sent artillery shells to Moscow.

Last week, National Security Council spokesperson John Kirby accused North Korea of covertly supplying a 'significant number' of the ammunitions to Russia. He said the United States believes North Korea was trying to obscure the transfer route by making it appear the weapons were being sent to countries in the Middle East or North Africa.
