Newsbuka.com has learnt that North Korea has confirmed it successfully tested a new submarine-launched ballistic missile on Tuesday.
Reports say the missile had advanced control guidance technologies, which could make it harder to track by anybody.
Meanwhile, North Korea has carried out a flurry of weapons tests in recent weeks, launching what it said were hypersonic and long-range weapons.
Recall that UN prohibits North Korea from testing ballistic missiles and nuclear weapons.
