North Korean leader Kim Jong Un and his wife, Ri Sol Ju, were among the hundreds in Pyongyang on Sunday watching South Korean K-pop singers perform in the North for the first time in more than a decade as tensions between the two countries thaw.

It was the first time a North Korean leader had attended a South Korean performance in the capital. Kim was seen clapping in tune to some of the songs and later took photographs with the performers after the show.

"Our dear leader comrade said his heart swelled and he was moved by the sight of his people deepen their understanding of South Korean popular culture and cheer with sincerity," said the North's state media.
