SEOUL, South Korea, Nov 20, (AP): North Korea recently supplied additional artillery systems to Russia to support its war efforts against Ukraine, while some of the thousands of North Korean troops deployed in Russia have begun engaging in combat, South Korea’s spy agency told lawmakers Wednesday. The South Korean assessment came after Russia warned Monday that US President Joe Biden’s decision to let Ukraine strike targets inside Russia with U.S.-supplied longer-range missiles adds "fuel to the fire” of the war.

US officials said Biden’s decision was triggered almost entirely by North Korea’s entry into the war. In a closed-door briefing at parliament, the National Intelligence Service said that North Korea exported 170mm self-propelled guns and 240mm multiple rocket launch systems to Russia, according to lawmaker Lee Seong Kweun, who attended the meeting. Lee told reporters that the NIS assessed those weapons are a type of artillery the Russian military doesn’t operate so North Korea likely dispatched personnel to teach the Russians how to use them and handle their maintenance.

Last week, Russian Telegram channels and other social media posts published photos apparently showing North Korean’s "Koksan” 170mm self-propelled guns being moved by rail inside Russia. The Financial Times, citing Ukrainian intelligence assessments, reported Sunday that North Korea in recent weeks sent some 50 domestically produced 170mm self-propelled howitzers and 20 240mm multiple launch rocket systems to Russia.

The artillery systems are the latest conventional weapons that North Korea is believed to have provided to Russia as the two countries are sharply expanding their military cooperation in the face of separate confrontations with the U.S. and its allies. Last month, the NIS said that North Korea had sent more than 13,000 containers of artillery, missiles and other conventional arms to Russia since August 2023 to replenish its dwindling weapons stockpiles.
