North Korean leader Kim Jong-un has reportedly paid tribute to his father Kim Jong-il on the sixth anniversary of his death.

The North's official Korean Central News Agency(KCNA) reported that Kim paid a visit to the Kumsusan Palace of the Sun in Pyongyang on Sunday. This mausoleum is the resting place for the North Korean leader’s grandfather and father. 

The report said that Kim used the anniversary to pay his respects at the statues of former leaders Kim Il-sung and Kim Jong-il. 

There was no mention in the report whether senior officials of the ruling Workers' Party or the military accompanied Kim on the visit to the palace. 

The KCNA had reported on Sunday that senior officials of the party and the parliament paid tributes at the palace, but did not mention if Kim attended, raising speculation that Kim didn't visit the palace on his father's anniversary.
