North Korea: Kim Jong-un oversees huge military showcase

The North Korean leader Kim Jong-un has overseen a huge display of his country's military personnel and equipment.

State media broadcast the parade and described a new type of submarine-launched ballistic missile as "the world's most powerful weapon".

The show of military strength comes days before the inauguration of Joe Biden as US president.

Mr Kim has recently decried the US as his country's "biggest enemy".
