North Korea said it successfully tested a new tactical ballistic missile on Monday capable of carrying a 4.5-ton super-large warhead, state news agency KCNA reported on Tuesday.
A day earlier, South Korea reported the launch of two ballistic missiles by North Korea and said the second likely failed soon after launch, blowing up in flight over land.
The KCNA report did not make clear if two missiles were launched and referred to the projectile in a singular term.
