North Korea has reportedly test-fired four ballistic missiles from Tongchang-ri, a region in the country's North Pyongan province, towards Japan.

The latest missile test involved intermediate-range missiles, CNN reported citing a US official.

According to military officials from South Korea, Japan, and the US, the missiles flew close to 1,000km after being launched on Monday.

South Korea's Joint Chiefs of Staff (Jcs) said that the missiles reached a height of 260km.

Japan Prime Minister Shinzo Abe was quoted by CNN as saying that three of the four missiles fell into Japan's exclusive economic zone.

"The launches are clearly in violation of UN Security Council resolutions."

Reuters quoted Abe as saying: "The launches are clearly in violation of UN Security Council resolutions. It is an extremely dangerous action.”

The UN Security Council Resolutions has prohibited North Korea's launches using ballistic missile technology.

South Korea Acting President Hwang Kyo-ahn condemned North Korea’s latest missile launches into the sea of Japan.

The missile launch is believed to be in response to joint military exercises being conducted between South Korea and the US.

South Korea's Office of Joint Chiefs of Staff said: "South Korea and the US are conducting a close-up analysis, regarding further information.”

The US military said that the North Korean missile launch does not pose a threat to North America.
