Recent satellite photos show a sharp increase in rail traffic along the North Korea-Russia border, indicating the North is supplying munitions to Russia, according to a U.S. think tank.
Speculation about a possible North Korean plan to refill Russia's munition stores drained in its protracted war with Ukraine flared last month, when North Korean leader Kim Jong Un traveled to Russia to meet President Vladimir Putin and visit key military sites. Foreign officials suspect Kim is seeking sophisticated Russian weapons technologies in return for the munition to boost his nuclear program.
