North Korea is believed to have shipped some 33,000 containers of military supplies, including weapons and ammunition, to Russia as part of its support for Moscow in the war with Ukraine, a military intelligence unit said Sunday. The shipped volume, in terms of ammunition, could amount to over 15 million 152-mm artillery shells, the Defense Intelligence Agency (DIA) under the defense ministry said in a report submitted to Rep. Kang Dae-sik of the main opposition People Power Party. The assessment marks an increase from the DIA's announcement in July last year that about 28,000 containers of military supplies had been shipped from North Korea to Russia. North Korea is known to have mostly used Rajin Port near the border with Russia to ship the containers via sea routes. North Korea is also believed to have supplied 220 artillery pieces, including 170-mm self-propelled howitzers and 240-mm multiple rocket launchers, Kang's office said, citing the DIA report. Additionally, North Korea is presumed to be shipping other weapons, including 122-mm and 152-mm shells, anti-tank missiles, short-rang
