The United States is condemning the Democratic People's Republic of Korea (DPRK)'s latest missile launch, calling it a destabilizing act. Pyongyang on Tuesday fired at least one ballistic missile from a submarine of its eastern coast. Washington says the launch posed no threat. But it's the country's latest weapons test as it pushes forward with military advances despite international sanctions over its nuclear program. This comes as envoys from Republic of Korea (ROK), Japan and the United States are meeting in Washington to discuss the tensions.
