SEOUL, Nov. 20 (UPI) -- North Korea could deploy up to 100,000 troops to aid Moscow in its war against Kyiv, Ukrainian President Volodymyr Zelensky warned, amid reports that the North was also sending additional long-range artillery systems to Russia.

Ukraine said on Monday (November 11) its hard-pressed military was battling 50,000 troops in Russia's Kursk region to its north. FRANCE 24's Gulliver Cragg tells us more.

Ukraine's president says the incursion is limiting the forces Moscow can deploy inside his country.
