North Korea test-fired a ballistic missile, South Korea's and US militaries said — defying intense pressure from the United States and the reclusive state's main ally, China.
US and South Korean officials said the test, from an area north of North Korea's capital Pyongyang, appeared to have failed, in what would be a fourth successive unsuccessful missile test since March.
The test came as US Secretary of State Rex Tillerson warned the United Nations that failure to curb North Korea's nuclear and ballistic missile programs could lead to "catastrophic consequences".
