Ukrainian intelligence believes that North Korea is sending thousands of its own soldiers to fight for Russia against Ukraine, a source tells NBC News.

North Korea is testing its new weapons on Russia’s side in the war, and Ukrainian officials say the North’s troops are also gaining direct battle experience.

A year and a half after the invasion of Ukraine, the Russian leader was meeting the North Korean dictator at a cosmodrome in the Russian Far East to exchange favors. What seemed like a desperate measure — turning to one of the poorest and most isolated countries on the planet — was also logical: Pyongyang’s huge Soviet-era arsenals could feed the Russian military machine.

Ukrainian President Volodymyr Zelenskyy said he had been briefed by Ukrainian intelligence services about what he described as North Korea's "effective involvement" in Russia's war in his country.

North Korea is sending its citizens to help Russia’s military fight Ukraine, Volodymyr Zelensky has said, increasing concerns about the alliance between Moscow and the secretive state.

Russia's war in Ukraine may have reached a new stage this week, with reports that North Korea has moved from supplying Moscow with weapons to sending its own troops. A Western diplomat familiar with the matter told the Kyiv Independent on Oct.

The U.S. says it is "concerned" about reports of North Korean soldiers fighting alongside Russian troops in the war against Ukraine, calling it "a new level of desperation."
