North Korea unveils new submarine-launched missile - BBC News

North Korea has unveiled a new type of submarine-launched ballistic missile, described by state media as "the world's most powerful weapon".

Several of the missiles were displayed at a parade overseen by leader Kim Jong-un, reported state media.

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

It also follows a rare political meeting where Mr Kim decried the US as his country's "biggest enemy".

Images released by North Korean state media showed at least four large black-and-white missiles being driven past flag-waving crowds.
