North Korean leader watches extreme martial arts performance

In the video aired by the North's state-run television station, KRT, soldiers performed multiple shows of strength: smashing items, breaking free from chains, lying on glass and throwing knives. Kim smiled and clapped as he watched the show at the Defence Development Exhibition 'Self-Defence-2021'. During the exhibition, Kim said his country's weapons development is necessary in the face of the US' hostile policies and a military buildup in South Korea.
