North Korean leader Kim Jong-un visited the Kumsusan Palace of the Sun on Thursday to mark the 73rd anniversary of the nation’s founding. 

The North's official Korean Central News Agency(KCNA) reported on Friday that Kim visited the palace along with his wife Ri Sol-ju on the occasion of the anniversary. 

Ri's public appearance is the first since May 5 when she attended a concert. 

Kim has paid tribute on major anniversaries at the palace in Pyongyang, where his grandfather and the North's founder Kim Il-sung and his father Kim Jong-il lie in state. 

Kim was accompanied by senior North Korean officials, including Choe Ryong-hae, chairman of the Standing Committee of the Supreme People's Assembly, Jo Yong-won, the secretary of the Workers' Party, and Premier Kim Tok-hun.

Kim also took a photo with the participants of a military parade held at 12 a.m. Thursday.
