First traffic observed on North Korea-Russia railway link in several years - mediaThat's according to 38North, Ukrinform reports.It is impossible to determine the purpose of the train from the imagery, but the crossing comes amid reports of arms sales from North Korea to Russia and a general expectation of the resumption of trade between the two countries.The 800-meter Tumangang Friendship Bridge (Korea-Russia Friendship Bridge) is the only land link between the two countries, and before the COVID-19 pandemic, it served a limited amount of rail traffic between Russia and the Democratic People’s Republic of Korea (DPRK).On Wednesday, White House National Security spokesperson John Kirby said that the US believes North Korea is sending shipments through the Middle East and North Africa in an attempt to disguise them.While this is the first train observed on satellite imagery traveling between the DPRK and Russia, it does not mean it is the only train that has crossed in recent months."
