North Korea has fired what appeared to be a ballistic missile towards the sea off its east coast from Sunan airport in Pyongyang, South Korea's Yonhap news agency has reported.
The launch comes 18 days after North Korea fired two "new tactical guided weapons" in the city of Hamhung. It was the country's 14th armed demonstration of the year.
In a speech at a military parade last week, North Korean leader Kim Jong-un said his nuclear force was not only tasked with preventing war through deterrence, but potentially carrying out strikes against anyone who violates the North's "fundamental interests.''
