North Korean leader Kim Jong-un visited a mausoleum for his deceased father and grandfather on Monday to mark the 101st birthday of the founder of the communist country, Pyongyang's official media said.

Accompanied by members of the country's top military brass, Kim made the visit to the Kumsusan Palace of the Sun in Pyongyang to pay "high tribute and humblest reverence" to former leaders Kim Il-sung, the country's founder, and his son Kim Jong-il, the Korean Central News Agency (KCNA) reported.

The Kumsusan Palace in Pyongyang is the place where the embalmed bodies of the late leaders lie in state. The incumbent leader took over the country after the sudden death of Kim Jong-il in late 2011. Kim Jong-il had also inherited the country after the death of his father Kim Il-sung in 1994. The founder's birthday, also called the Day of the Sun, is the most important holiday in the North.

Kim Jong-un, who holds the title of first secretary of the Workers' Party of Korea (WPK), is the first chairman of the DPRK National Defense Commission and supreme commander of the Korean People's Army,

DPRK stands for the Democratic People's Republic of Korea, the North's official name.

According to the KCNA, Kim and senior military officers presented floral baskets in the name of the WPK's Central Military Commission and National Defense Commission, with ribbons bearing a message that read, "The great Comrades Kim Il-sung and Kim Jong-un will always be with us."

Besides the leader, senior generals and officials such as Choe Ryong-hae, the director of the military's General Political Bureau, and Jang Song-thaek, Kim's uncle and widely viewed as the No. 2 man in the country, were present at the event that took place at midnight. (Yonhap News)
