North Korea has test fired a suspected ballistic missile, days after the reclusive nation vowed to further strengthen its nuclear arsenal.

The ballistic missile was fired from the Sunan area of the North Korean capital of Pyongyang towards the eastern waters, Reuters reported, quoting South Korea’s Joint Chiefs of Staff (JCS).

The missile reached an altitude of 780km and travelled approximately 470km.

This is North Korea’s 14th known weapons test this year. It comes just days before South Korea’s newly elected president Yoon Suk-yeol assumes responsibility.

“A recent series of North Korea’s ballistic missile launches poses a grave threat to the peace and stability of not only the Korean peninsula, but also the international community,” Reuters quoted JCS as saying in a statement.

The test was also condemned by the US and Japan.

Using the acronym of North Korea’s official name, the US Indo-Pacific Command said: “We are aware of the DPRK’s ballistic missile launch today and are consulting closely with the Republic of Korea (ROK) and Japan, as well as other regional allies and partners. 

“The United States condemns these actions and calls on the DPRK to refrain from further destabilising acts. While we have assessed that this event does not pose an immediate threat to US personnel, territory, or that of our allies, we will continue to monitor the situation.”

In March, the US increased its surveillance and reconnaissance collection in the Yellow Sea following a series of missile tests by North Korea.
