North Korea tried and failed to test-fire what appeared to be a medium-range Musudan missile on the birthday of founding leader Kim Il-Sung Friday, a high-profile misstep after Pyongyang claimed a series of breakthroughs in its nuclear weapons programme.
The missile disappeared from surveillance radar a few seconds after launch and is believed to have exploded midair, said a Seoul intelligence official quoted by Yonhap news agency.
There had been widespread intelligence reports in recent days that the North was preparing for the first-ever flight test of its Musudan missile, which is believed to be capable of striking US bases in the Pacific island of Guam.
The US and South Korean militaries both detected and tracked the early morning test.
“We assess that the launch failed,” a US defence official said, adding that it was “presumably” a Musudan.
The April 15 birthday of Kim Il-Sung — the grandfather of current ruler Kim Jong-Un — is a major public holiday in North Korea, where key political anniversaries are often marked with displays of military muscle.
The country is also gearing up for a rare and much-hyped ruling party congress next month, at which Kim Jong-Un is expected to take credit for pushing the country’s nuclear weapons programme to new heights.
Pyongyang has hailed a series of achievements in recent months, including miniaturising a nuclear warhead to fit on a missile, developing a warhead that can withstand atmospheric re-entry, and building a solid-fuel missile engine.
Last week, it said it had successfully tested an engine designed for an inter-continental ballistic missile (ICBM) that would “guarantee” an eventual nuclear strike on the US mainland.
Outside experts have treated a number of the claims with scepticism, while acknowledging that the North’s nuclear and ballistic missile programmes have both made significant strides.
If Friday’s failure is confirmed as a Musudan test, it would mark a very unwelcome public failure and fuel doubts about just how far the North has gone in developing a reliable nuclear delivery system.
“We are monitoring and continuing to assess the situation,” another US official said, calling on North Korea to “refrain from actions that further raise tensions in the region.”
Anxiety has been high on the divided Korean peninsula since Pyongyang conducted its fourth nuclear test in January and a rocket launch a month later that was widely seen as a disguised ballistic missile test.
The UN Security Council responded with its toughest sanctions to date, angering the North, which has since made repeated threats of attacks targeting the South and the US.
Existing UN resolutions forbid North Korea from the use of any ballistic missile-related technology.
Pyongyang, with the series of provocations, is trying to prove that the UN sanctions are ineffective in curbing its weapons development, said Seoul’s unification ministry, which handles cross-border affairs.
“They are trying to divide opinions of the international community by pushing more people to think that we… need dialogue with the North,” ministry spokesman Jeong Joon-Hee said.
