Ukrainian President Volodymyr Zelensky said on Sunday that defense relationships with his country's partners would have to change in light of North Korean transfers of people as well as weapons to Russian forces in Ukraine. The Kremlin on Thursday dismissed South Korean assertions that North Korea may have sent some military personnel to help Russia against Ukraine and might be weighing a bigger deployment. "We see that the alliance between Russia and such regimes as the North Korean one is getting stronger," Zelensky said in his nightly video address. "This is not just about the transfer of weapons, this is in fact about the transfer of people from North Korea to the armed forces of the occupiers. South Korea's Defense Minister Kim Yong-hyun said on Tuesday that "there was a high possibility" North Korea could deploy troops to help Russia in the war with Ukraine. Kremlin spokesman Dmitry Peskov, asked on Thursday if North Korea was sending its troops to fight in Ukraine, told reporters: "This looks like another bit of fake news."
