North Korea has confirmed it successfully tested a new submarine-launched ballistic missile on Tuesday.

State news outlet KCNA said the missile had "advanced control guidance technologies", which could make it harder to track.

North Korea has carried out a flurry of weapons tests in recent weeks, launching what it said were hypersonic and long-range weapons.

The UN prohibits it from testing ballistic missiles and nuclear weapons.

Ballistic missiles are considered more threatening than cruise missiles because they can carry more powerful payloads, have a longer range and can fly faster.
