The Democratic People's Republic of Korea (DPRK) fired an unidentified ballistic missile off its east coast Wednesday morning, according to South Korea's Joint Chiefs of Staff (JCS).

The South Korean military spotted the unidentified ballistic missile, which was launched from the waters northeast of the DPRK's eastern coastal town of Wonsan in the eastern direction at about 7:11 a.m. local time, the JCS said in a statement.

It was estimated to have been a Pukkuksong type of submarine-launched ballistic missile (SLBM), the JCS said.

The missile flew about 450 km at a maximum altitude of around 910 km. The intelligence authorities of South Korea and the United States were precisely analyzing its further details.

The JCS said the South Korean military was monitoring relevant situation in case of additional firings and maintaining readiness posture.

It urged Pyongyang to immediately stop such acts that are of no help for efforts to defuse tensions on the Korean Peninsula.
