SEOUL, South Korea - A North Korean medium-range missile exploded seconds after it was launched on Sunday, U.S. officials said, a high-profile failure that came hours before the U.S. vice president arrived in South Korea, and as an American aircraft supercarrier approaches the Korean Peninsula in a show of force. The failed launch from North Korea's east coast, ignoring admonitions from major ally China, came a day after North Korea held a military parade in its capital, marking the birth anniversary of the state founder, in which what appeared to be new long-range ballistic missiles were on display. North Korea attempted to launch a missile that is believed to have failed, the U.S. Pacific Command confirmed on Saturday.

In a broadcast interview that aired on Sunday, McMaster said the U.S. would rely on its allies as well as on Chinese leadership to resolve the issues with North Korea.
The U.S. Pacific Command and South Korea's Joint Chiefs of Staff report that a North Korean missile, tested near the city of Sinpo on the country's east coast, blew up almost immediately after the launch, just hours before U.S. Vice President Mike Pence was due in South Korea for talks about the North's arms program.
