North Korea test fires submarine-launched ballistic missile

North Korea on Wednesday morning successfully test fired a new ballistic missile.

As per South Korea's military, the missile was launched from a submarine in the Sea of Japan, off North Korea's eastern coast. The test comes a day after the United States and South Korea launched joint military exercises on the peninsula.

The projectile reached Japan's air defence identification zone (ADIZ), an area of control designated by countries to help maintain air security, South Korea's Yonhap News Agency reported.

Pyongyang had warned against the drills, threatening to launch a pre-emptive nuclear strike. North Korea has test fired a number of ballistic missiles in recent months, and has also conducted nuclear tests.

Condemned by the international community, these resulted in the implementation of harsh new sanctions by the United Nations.
