Kim Jong Un reviews troop parade on N. Korea armed forces day

North Korean leader Kim Jong Un reviewed a troop parade in Pyongyang on Thursday as the country marked the 81st anniversary of the founding of the Korean People's Army, its 1.2 million-strong military, an informed source said.

Marching soldiers pledged allegiance to KPA Supreme Commander Kim at a military ceremony at the Kumsusan Palace of the Sun, a mausoleum of state founder Kim Il Sung and his son and former leader Kim Jong Il in Pyongyang, the source told Kyodo News.

The event, which apparently was not open to the public, did not involve the procession of major weapons and military hardware such as ballistic missiles, according to the source.

The event appeared to be aimed at strengthening unity of the military and the people around the young leader amid heightened tensions with other regional powers such as the United States, South Korea and Japan over Pyongyang's nuclear and missile programs.

Usually, North Korea stages a military parade at Kim Il Sung Square, the main plaza in the capital named after the country's founder.

Kim Jong Un came to power after the death of his father and longtime ruler Kim Jong Il in December 2011.
