Ukraine's President Volodymyr Zelensky on Sunday publicly condemned increasing Russian-North Korean collaboration regarding Moscow's war in Ukraine, which Zelensky for the first time said hasn't stopped at providing arms, but has even witnessed Korean troops present in the battle zone.

"We see an increasing alliance between Russia and regimes like North Korea. This is no longer just about transferring weapons. It is actually about transferring people from North Korea to the occupying military forces," Zelensky stated.
