TV images show a huge military memorial parade was held in the capital city and tens of thousands of people were seen on the Kim Il Sung Square.

The official KCNA said Kim Jong Un, vice-chairman of the Central Military Commission of the the Workers' Party of Korea and supreme leader of the party, state and army of the country, took the platform.

KCNA reported last week that at the memorial service, "mourning guns will be boomed in Pyongyang and in provincial seats timed to coincide with the national memorial service in Pyongyang."

"All the people will observe three minutes' silence and all locomotives and vessels will blow sirens all at once," said the report.

On Wednesday, the DPRK held a state funeral for the demised leader, who died from "great mental and physical strain" on a train during a field guidance tour.
