North Korea today confirmed that it launched a new missile from a submarine and considered this test "an important achievement" in the face of threats from "outside forces."

Pyongyang's official agency, the KCNA, confirmed the information released today by South Korea about launching a ballistic missile from a submarine (SLBM), although it did not disclose details about its trajectory.

KCNA also explained that this is the third version of its Pukguksong (Polar Star) missile and said the launch was made from Wonsan Bay on the east coast of North Korea.

South Korean military sources announced today that North Korea fired at least one projectile off its east coast, in what appears to be a demonstration of increasing military capability before nuclear talks with the United States.

The joint command of South Korea's chiefs of staff did not immediately confirm the type of weapons fired or the distance traveled.

The launch comes after a senior North Korean diplomat said on Tuesday that North Korea and the US had agreed to return to nuclear dossier negotiations.

Negotiations have been stalled for months after the collapse of a summit between North Korean leader Kim Jong Un and US leader Donald Trump over disagreements over the disarmament lifting of sanctions.
