Ukrainian President Volodymyr Zelensky confirmed that North Korean troops have rejoined Russian forces at the Kursk front line after a temporary withdrawal due to heavy casualties. He noted extensive casualties among both Russian and North Korean soldiers during recent assaults. The presence of North Korean forces is attributed to strengthened bilateral ties between Pyongyang and Moscow, which include military support amidst the ongoing conflict. Reports indicate that the North Koreans were unprepared for modern warfare, leading to significant losses that threaten their sustainability in combat operations.
