North Korea has reportedly test-fired a ballistic missile from Sinpo, a port city on the coast of the Sea of Japan.
The latest missile test, which involved a medium-range missile, comes ahead of a summit between US President Donald Trump and China's President Xi Jinping, according to media sources.
Reuters quoted a South Korean official as saying: "The launch took place possibly in consideration of the US -China summit, while at the same time it was to check its missile capability.”
South Korea's Joint Chiefs Of Staff (JCS) said that the missile flew close to 60km after being launched on Wednesday.
The missile reached a height of 189km, reported a South Korean official.
According to the US and South Korean militaries, the missile is believed to be a KN-15 medium-range ballistic missile.
Commenting on the test, US Secretary of State Rex Tillerson said: "The US has spoken enough about North Korea. We have no further comment."
South Korea has condemned the ballistic missile launch by North Korea, noting that the act violated resolutions made by the UN Security Council.
South Korea Foreign Ministry was quoted by Reuters as saying: "This is a blunt challenge to a series of Security Council resolutions... and an act to threaten the peace and safety of the international community as well as the Korean peninsula.”
