Pyongyang has ratcheted up its support for Russia following Russian President Vladimir Putin’s signing of a mutual defense pact with North Korean leader Kim Jong Un in June.Earlier reports mentioned more than 5 million artillery shells and 100 short-range ballistic missiles, including short-range ballistic missiles of the KN-23/24 type, supplied to Russia."Their accuracy, in principle, is not very high. We understand that the technology with which they were manufactured is outdated," Andrii Cherniak, a military intelligence spokesperson, told Radio Free Europe/Radio Liberty.On top of ammunition and missiles, since late October, thousands of North Korean troops have been fighting in Russia’s Kursk Oblast to expel Ukrainian forces holding approximately 800 square kilometers (309 square miles) of Russian territory.According to President Volodymyr Zelensky, they suffered their first losses.
