North Koreans danced in Pyongyang to mark the third anniversary of its leader Kim Jong-un's appointment as the Supreme Commander of the country.

In video provided to Reuters by the North's official news agency KCNA, which cannot be independently verified, hundreds of men and women were seen dancing together to celebrate three years since Kim Jong-un came to power.

Kim was appointed as a Supreme Commander of its 1.2 million-strong military in 2011, just after the state's former leader and his father Kim Jong Il died.

The Interview, an American comedy film about an attempt to assassinate Kim Jong-un, was initially pulled from theatrical release after a cyber attack on the studio behind the film, Sony Pictures, was attributed by the United States government to North Korea.
