North Korea is marking the second anniversary of the death of leader Kim Jong-il, days after the dramatic purge of a top-level official.
Images from Pyongyang showed ranks of thousands of officials at a ceremony to commemorate Mr Kim.
His son, Kim Jong-un, inherited the leadership after his death in 2011.
Last week he presided over the execution of Chang Song-thaek, his uncle and a powerful figure seen by outside observers as his mentor.
Mr Chang was accused of multiple crimes, state media said, including forming a power base and attempting to overthrow the state.
