North Korea has claimed that it successfully tested a new hypersonic missile called Hwasong-8 on Tuesday.

State media said the new missile was one of the "five most important" new weapons systems laid out in its five-year military development plan.

They called the missile a "strategic weapon", which usually means it has nuclear capabilities.

Tuesday's launch is another indication of Pyongyang's growing weapons technology amid strict sanctions.

"The development of this weapons system...[has increased] the nation's capabilities for self-defence in every way," North Korean state news outlet KCNA said.

The latest launch also marked the country's third missile test this month. It has already revealed a new type of cruise missile, as a well as a new train-launched ballistic missile system.
