North Korea has not responded to reports of its troops captured or killed by Ukraine forces.

Andriy Kowalenko, head of the Centre for Counteracting Disinformation at the National Security and Defence Council of Ukraine, reported that Russia is increasingly dependent on artillery supplies from North Korea.
