Nuclear-armed North Korea launched an apparent intercontinental ballistic missile and two other ballistic missiles on Wednesday, South Korea's military said, just a day after U.S. leader Joe Biden wrapped up his first visit to Asia as president.

Seoul said the suspected ICBM had a range of around 360 kilometers, hitting an altitude of around 540 km. The second launch was thought to have exploded midair, while the third test was believed to have been of a short-range ballistic missile that flew 760 km and hit a maximum altitude of 60 km.

The South Korean military said all of the missiles were fired from the Sunan area of Pyongyang, where the North has been known to test its ICBMs.
