A photo circulating on social media shows North Korean artillery pieces that have been shipped to Russia as Pyongyang continues to support Moscow’s war against Ukraine. A Russian Telegram channel published the photo on Thursday, showing two guns being transported by rail. They have been identified as North Korean M1989 Koksan 170 mm self-propelled howitzers.

According to specialist outlet The War Zone, the M1989 can store 12 shell rounds and has a range of between 25 to 37 miles. The photo caption reads: “We have an ally who fulfills agreements, for which we are very grateful.” Russia and North Korea ratified a defense treaty recently, which mandates them to deploy available military resources to assist if either side is attacked. Newsweek has reached out to both the foreign and defense ministries in Moscow, as well as the North Korean Embassy in Beijing for comment via email.

Ukraine and its Western allies have accused North Korea of sending troops to support Moscow’s so-called special military operation in Ukraine. According to the US, about 10,000 North Korean forces have been sent to Russia and have begun military operations. In addition to artillery and manpower support, North Korea has provided Moscow with other weapons. Ukraine claimed in September that it destroyed “significant stocks” of North Korean ballistic missiles during a massive drone strike on a Russian military depot. Status-6, a social media account that monitors military and war news, stated that the shot was taken in Krasnoyarsk, a city in central Russia. It is also one of the stops of the Trans-Siberian Railway, which connects European Russia to the Russian Far East.
