The missile flew only “for several minutes” to the northeast, reaching an altitude of 44 miles, the South Korean military said. It provided no further details.
It was the North’s first test since the government of Kim Jong-un launched a ballistic missile near its submarine base on North Korea’s east coast on April 16. That launch was also a failure, with the projectile exploding just after liftoff.
In a statement, White House officials said that President Trump had been briefed on the launch. Mr. Trump said on Twitter: “North Korea disrespected the wishes of China & its highly respected President when it launched, though unsuccessfully, a missile today. Bad!”
The test on Saturday came hours after Secretary of State Rex W. Tillerson led a ministerial meeting of the United Nations Security Council on Friday. Referring to North Korea’s advancing nuclear and missile programs, Mr. Tillerson warned that “failing to act now on the most pressing security issue in the world may bring catastrophic consequences.”
The world has been watching North Korea closely in the past several weeks, amid fear that the country might attempt its sixth underground nuclear test. Satellite imagery of the nuclear test site in the country’s northeast showed that the North was ready for a test, analysts said.
But the country has so far refrained from conducting a nuclear test or launching one of its intercontinental ballistic missiles under development to mark major anniversaries in April. Instead, it celebrated those anniversaries with a military parade featuring new missiles and a massive live-fire drill.
It remained unclear what has caused the series of missile test failures.
Over the past three years, a covert war over the missile program has broken out between North Korea and the United States. As the North’s skills grew, President Barack Obama ordered a surge in countermeasures against the missile launches, The New York Times reported last month, including through electronic-warfare techniques.
It is unclear how successful the program has been, because it is almost impossible to tell whether any individual launch failed because of sabotage, faulty engineering or bad luck.
North Korea rattled the region in February by successfully launching a new intermediate-range ballistic missile that it said could carry a nuclear payload. That missile, the Pukguksong-2, uses a solid-fuel technology that…
