North Korea stages military parade on eve of Olympics
Thousands of troops had trained for the parade.
North Korea has held a military parade and rally on Kim Il Sung Square a day before South Korea holds the opening ceremony for the Pyeongchang Winter Olympics.
More than 10,000 troops had trained for the parade in advance.
Residents practised in plazas around the North Korean capital, with bouquets of plastic flowers used to spell out slogans during the parade.
A South Korean government official said tens of thousands of people participated or watched the parade on Thursday morning in Pyongyang.
The official said it was not immediately clear whether North Korea displayed strategic weapons, such as intercontinental ballistic missiles, during the parade.
The North had said the parade would mark the 70th anniversary of its military founding.
